Gmail app doesn't send messages, gives strange logcat message
Things like this sometimes happen when something gets stuck in cache. To solve that, the easiest approach is:


boot into recovery
select to "wipe cache"


Which works for both, stock recovery (aka "3E") and custom recoveries.

Of course, with a custom recovery you can also "wipe Dalvik" – doesn't hurt, just causes a longer first-boot after that. Side effect might even be improved performance, especially when you frequently install/update/uninstall apps, as this wipe forces the entire dalvik cache to be rebuilt cleanly. The important part however is the "normal cache", where it's more common that "things get stuck".
