Description Chris 2015-12-16 13:36:05 UTC 
Application: akonadi_imap_resource (4.89.0)

Qt Version: 5.5.0
Operating System: Linux 4.1.13-5-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
This has happened twice this morning.  The first crash locked up the keyboard and didn't allow me to finish this input.  ctrl, alt, backspace to logout and log back in lead back tothis crash.  I have also seen Mysql errors that say someting to the efect that Mysql cannot be reached.  Will try to add that log to this report.  May not be related except that the log hasn't changed since the last update.

The crash can be reproduced every time.

-- Backtrace:
Application: Akonadi Resource (akonadi_imap_resource), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 2 Daniel Vrátil 2017-01-07 13:11:30 UTC 
The crash in IMAP resource has been already fixed in some recent version. The MySQL error is due to MySQL data corruption (possibly because of the forced X crash?), nothing I can do about that.
