Comment 1 Martin Bednar 2016-09-04 18:28:56 UTC 
This just happened to me. KDevelop 5.0.0, KF 5.25, qt 5.6.1. The backtrace looks very similar.
Happens randomly.
Comment 2 Kevin Funk 2016-09-05 08:15:53 UTC 
Crash in KTextEditor, moving it to the right Bugzilla product.
Comment 3 Dominik Haumann 2016-09-05 10:14:52 UTC 
This will be fixed in upcoming KDE Frameworks 5.26, sorry for the inconvenience.
