Q: iTunes 10.6 crashing after upgrade

Thanks. Are the files in the iTunes music folder that need to be restored the xml and itl files?

Certainly the itl file, not sure about the rest; I restored all of them and it now works.

Same problem for Mac os 10.6.8! Crash over and over again when I clicked the sidebar icons such as music and podcast. 

Continuing on the standard troble shooting train, I took all iTunes plist files and moved them from the Prefs folder to a holding folder and restarted iTunes. It asked me to agree to the new license (so far so good) and then started up. Plugged in the iPad, clicked on it, clicked on Apps, Kaboom.

Apple, if you're listening, does the term regression testing mean anything to you...? How in the world did this get through?

I have the same problem, but it is only crashing when I try and select my iPhone in the sidebar, OR if I choose Sync from the file menu, it starts the sync, gets to step 6 and then crashes. The iPhone seems to be functioning fine; I've restarted it but not tried a total reset yet. And, strangely, it seems to have synced okay, but it would be nice to be sure of that and also be able to sync without crashing iTunes every time...

This is not happening with my iPad.

Running OS X 10.7.3, iPhone 4 with iOS 5.1, iTunes 10.6, no iTunes plug-ins installed...

Downgraded to 10.5.3 using TimeMachine (thankyou davidashe for the instructions) and all is back to normal.

Ok, I posted above. Crashes every time I started the new iTunes. Called Apple Tech Support and got a WONDERFUL technician - thank you J!. Nothing worked. It would have been so easy if I had a Time Machine backup of my Applications folder, but only backed up my user folder. There's no earlier version of iTunes on the Apple site. I started file sharing on my wife's Mac and mine, copied iTunes on her Mac (which I had thankfully NOT upgraded) to mine. Trashed the new iTunes using the Command I approach above and edited the permissions. Got rid of the com.apple.itunes.plist file. Opened iTunes and the earlier version was back, but no playlists! So, I restored the iTunes Music folder from my iTunes Time Machine backup and everything works now. That was an hour and a half on the phone. But worth it. I can't blv Apple released this dog to the public without checking to see if it actually works, etc.

Thx you Mr. Ashe... the info is right on. I just did this and also had to restore my iTunes Music folder and it all works.

Look at the crash report. Show Details and read down a few lines. Next to Exception Type: and Exception Codes, you will see Crashed Thread: Number.

Go to that thread and see its last operation.

For me, the last operation is always a libRIP operation, usually one of the two:

ripc_DestroyEntry

ripc_RemoveEntry

A quick Google shows that iTunes has had crash bugs involving the libRIP library before. It appears to be related to cover art display.

Sure enough, my iTunes 10.6 is crashing mainly when I view TV Shows, Podcasts, Movies, or Music in album art mode.

(It crashed continuously at startup until I managed to click fast enough and use Option+Command+3 fast enough to get to a list view).

A quick google for "iTunes ripc_RemoveEntry" shows that some German iTunes users are experiencing this crash too, and it appears to have been fixed once but has now reappeared.

Having recreated my iTunes library, I no longer have any crashes on startup.

However, just now I tried changing the zoom level on the album art and...crash! (Same as before).

So, I won't be changing the zoom level.

I was in the exact same boat as gregmorris. I called AppleCare and here is a temporany solution which allowed me to back up my phone, access it when hitting the phone icon within iTunes and not cause a crash, and upgrade if desired. During the process to figure out what was wrong, we created a new login on my MacBookPro and accessed iTunes as usual. When I plugged in my phone, no crash, even when clicking on the phone icon in the iTunes menu. After verifying the stability of iTunes in combination with my iPhone plugged in, I copied all of my music and media, the .itf file and my last iPhone backup that was made right before upgrading to iOS 5.1 to the dropbox. I was able to access these files from my new login, change the permissions to the files and sync and backup my iphone without incident.

It is not a perfect solution, but it is a way for me to keep backing up my phone as usual until a permanent solution is devised. I hope this helps.

Take any movie, start playing in a small window.  Click on the full screen arrows and kaboom - crash.

Apple's software QA is atrocious and discouraging.

After 3 hours, the only thing that actually works was restoring from Time Machine... Thanks for posting how to do it!
