Mail app keeps crashing

[StructAural]

I use Mark unread addon to quickly mark all my mail as read. I went to use it today and it crashed Mail. Resprung and Mail is still crashing back to Home screen.

Is there a file that can get corrupted that i could SSH in and remove?
Anyone had this problem?

Rebooted too, same result, can't get into my mail anymore...help!

Uninstall the add-on and respring. If that doesn't fix it (or re-installing the add-on) you're most likely looking at a restore

Phew solved it!

I deleted
/User/Library/Preferences/com.apple.mobilemail.plist
and it is all back to normal.

Didn't need to delete tweak either, which normally works just fine.

Glad I didn't need to restore...
