The new version of Pages consistently faults on calls to "com.apple.MediaLibraryService". Is this a known issue, and are there workarounds?

OS X Mavericks (10.9)

I rebooted in Safe Mode. Launched Pages (with a blank page) and Numbers (with 3 small, simple spreadsheets I use regularly).


In Safe Mode:

com.apple.MediaLibraryService 1.35 GB (first instance)

com.apple.MediaLibraryService 1.35 GB (second instance)

Numbers 517.6 MB

Pages 485.5 MB


After restarting:

com.apple.MediaLibraryService 1.35 GB (first instance)

com.apple.MediaLibraryService 1.35 GB (second instance)

Numbers 568.8 MB

Pages 507.7 MB


So, the proposed AppleCare remedy made things worse, if anything.

Seems to be a runaway process issue affecting Pages 5.1, Numbers 3.1, and iTunes 11.1.4 (possibly earlier).


Symptoms include app crashing with a message implicating com.apple.MediaLibraryService, noticeable performance slowdowns in iTunes and elsewhere (to the point of songs freezing skipping), and fans coming on due to heat generated by high processor utilization (I'm seeing 108% in a quad-Core i7 w/16GB RAM).


Googlecom.apple.MediaLibraryServicefor many other reports of the exact same problem.

I've also tried the safe mode, but even then the problem remains, so it is not a problem of third party sofyware. We definitely need an update for the new Pages and Keynote under Mavericks, because there is a serieus memory leak that consumes all resources until the MacBook is unworkable slow (especially if you open both apps at the same time). Only a reboot helps; that means I have to reboot every day! Apple, do something about his annoying bug. I'm an happy Apple user for years and for the first time I'm considering a swap to Windows again. Even Vista was more workable. I'm losing productivity!!!!!!!!!
