--- Comment #2 from Péter Ujfalusi <peter.ujfal...@gmail.com> --- Darren, Distro: Gentoo (~amd64) Kate Part: 5.38.0 Kate: 17.08.1 Kwrite: 17.08.1 Krusader: 2.6.0 KDevelop: 5.1.2 KDE Frameworks 5.38.0 Qt 5.7.1 (built against 5.7.1) I have not changed the highlighting preferences, not for Source/C for sure, I might have modified things for python. I can reproduce it with the 'blah.c' 100/100. If I recall correctly the editors started to crash more frequently after upgrading to 17.08.1, I have faint recollection of a crash with 17.08.1. Earlier (<=17.04.3) I don't think I have seen this. Out of desperation I have rebuilt everything related to the editors: emerge -1 --exclude app-office/libreoffice -aev kwrite krusader but it did not helped. >From Kate this is the backtrace I get (which is not really useful): Application: Kate (kate), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

() Tried gdb as well, but not much help from it either, I can not pin-point the library I need to rebuild with debug. -- You are receiving this mail because: You are watching all bug changes.
