Comment 1 Thomas Friedrichsmeier 2017-06-04 19:04:35 UTC 
Thanks for reporting, and sorry about the long delay.

Can you come up with a code that is likely to trigger the crash?

Thanks!
Comment 2 Thomas Friedrichsmeier 2018-04-17 08:29:08 UTC 
This is relatively likely to be a problem with the KDE 4 libraries, not directly in RKWard code. Therefore, whatever it was, it is rather likely to be fixed in RKWard 0.7.0, released, yesterday.

Are you still able to reproduce this bug with RKWard 0.7.0 or later? Also, can you provide more info as requested in comment #1 ?
Comment 3 Adley 2018-04-29 23:01:41 UTC 
Fedora hasn't provided RKward 0.7.0 yet. 
It seems to be fixed after update to the newer rebuild 
(I am using rkward-0.6.5-14, the 14th rebuild). Will update the status after upgrade to the 0.7.0. Thanks.
