Description Alexander 2012-08-26 16:30:18 UTC 
I'm using KDevelop/KDevPlatform git master from 2012-08-26.

Approximately once a day I see KDevelop crash when editing C++ sources. This happens when I move a line up or down using ctrl-shift-up or ctrl-shift-down, I think mostly when the line (with some definition) enters or exits a scope defined by curly braces.
I'm attaching a kcrashhandler-created backtrace below.

Thanks,
Alexander

Reproducible: Sometimes

Steps to Reproduce:
1. It's difficult to reproduce, but maybe you'll get "lucky":
2. Pick some source line which contains a definition.
3. Move it around with ctrl-shift-up or ctrl-shift-down, entering some if/for/while blocks, etc...



openSUSE 12.1 x86_64, KDE 4.7.2, Qt 4.7.4.
Comment 1 Niko Sams 2012-08-26 16:38:29 UTC 
this is a bug in QtScript. luckily already fixed - though we'll have to wait for Qt 4.8.3 to get the fix.
