*** This bug has been marked as a duplicate of bug 342752 ***

Comment 2 Rex Dieter 2015-08-08 22:42:45 UTC

$ rpm -q kf5-knotifications

please.

(pretty sure you probably have newer than 5.7.0, but need to know for sure to re-open the dup'd bug)

Comment 3 Rex Dieter 2015-08-08 22:46:37 UTC

Guessing this may also be a dup of bug #348414 (fixed after knotifications-5.12.0)

Comment 4 Garry Williams 2015-08-09 13:38:51 UTC

Comment 5 Garry Williams 2015-08-09 13:44:34 UTC

I cannot reproduce this crash now.

Comment 6 Rex Dieter 2015-08-09 15:07:07 UTC

OK, interesting.  Let us know if it ever happens again then.  Thanks.
