Call app needs long time to start
I have experienced the same issue on my Galaxy S2(Android version 2.3.5). It was cause by Youtube, not the call app. When I saw the log related to youtube, I tried to start youtube by touching its icon, but it failed to start. You can try to see if you can start youtube now.

Then I went to "Settings/Application/Manage Applications" and found "Youtube". Cleared its data and cache. Now try to start youtube again. If it cannot start, check if you has disabled data sync. Enable it in "Settings/Account and Sync/Background data". Try to sync your data to allow youtube to update. After youtube is updated, it should be ok for the call app to work properly.

Hope this can also fix your problem. Cheers.
