Comment 1 Torbjörn K. 2011-07-20 21:57:02 UTC
Created attachment 62037 [details]
GDB backtrace of this crash

How to reproduce:
 - create brand new session
 - imported source from kdeexamples (current clone of master)
 - try to open a *.cpp file
--> crash

Can be reproduced every time.
Comment 2 Milian Wolff 2011-07-20 23:00:12 UTC
that last crash is unrelated to the former backtrace. but helpful nonetheless (as it shows another issue we can see in our unit tests).
Comment 3 David Nolden 2011-07-21 11:32:12 UTC
Git commit b6001b7df6cba79cd030d020714a946d77915668 by David Nolden.
Committed on 21/07/2011 at 13:30.
Pushed by zwabel into branch 'master'.

Don't clear the area while switching the working-set as result of viewAdded().

This fixes possible crashes and makes the document-controller test work again.

Comment 4 David Nolden 2011-07-21 11:33:48 UTC
There is no way how StaticCodeAssistant::documentLoaded could lead to setPrettyName, therefore the backtrace of the report is borked.

Probably you have a compilation problem. Clear your build-directories and try compiling again.
