Evolution doesn’t run anymore. I deleted its config folders, but still no luck. I can’t find useful debugging info.

Error Message shown doesn’t give much info:

(“Evolution can not be started . Another instance of evolution could not respond . System error : timeout was reached”)

Neither does gdb:

Any help?
