Hi Phil! Sorry about my delay. Been a bit tired today, and it's been taking a while to hack through all the replies I have to make for the folks with cryptic troubles.
I've tried removing the preference files in turn as directed (on my Touch's iTunes) but iTunes still closed/crashed when selecting Podcasts. There are no plug-ins by the way, I did check the plug-ins folder.
Well, at least that's another couple of possibilities off the table.
So, I'm thinking we'd better check
content issues now.
One of the differences between the test account and the usual account will be the podcasts showing up in the podcasts pane (or at least, that
would show up in your usual account's podcast pane if only we could get in there without the ... "dratted" ... thing
crashing).
Sometimes iTunes crashes
can be caused by specific podcast files that are damaged in the right/wrong way ... especially
video podcasts. A few years ago, folks had some trouble with +Ask a ninja,+ and a year or so after that there were a few troubles reported with +Mad money+ (something to do with Jim Cramer, at least).
So maybe we might be able to isolate this to a specific (or at least specific
sort) of podcast feed that you're subscribed to.
Try heading back into your test user account again, and launching the iTunes there. *Remember to go to the "Devices" tab and make sure that "Prevent ipods and iphones from syncing automatically" is checked.*
(At this point I can't give
specific instructions because I don't do a lot of podcasting stuff ... so I'm just hoping that what I'm going to suggest makes sense.)
Try adding your
usual podcast subscriptions to the library in the test account
one-by-one. After each addition, try plugging the ipod/s in, and seeing if you can still get into the podcasts tab without crashing. After each "crash test", disconnect the iPod/s prior to doing the next addition.
Does a particular podcast addition suddenly start up the podcast crash in the test account?
