Comment 1 Milian Wolff 2012-10-04 23:07:05 UTC 
Invalid memory access (uninitialized data?).

If it's reproducible, maybe run through valgrind and give Sven a log so he can fix it:

valgrind --track-origins=yes kdevelop ...
Comment 2 Sven Brauch 2012-10-04 23:41:59 UTC 
Hi!

This is indeed a crash in the python plugin, but it has been a while since it was reported... and the offending code is gone. Can you check whether the problem can still be reproduced using a recent version of the plugin?

Greetings,
Sven

Reproducible on my side with kdev-python beta2-38-ga502a7d everytime, updating to newer version now:

Comment 4 Sven Brauch 2012-10-06 17:09:51 UTC 
Hi,

thanks for the backtrace. I tried to parse that file and a bit of other wxgtk stuff with beta2-49-ga616174, and it works fine here. I recently fixed a similar bug, can you update to beta2-48-5b9f77c41 or later? It will probably work there. Please let me know if not, then I'll investiage further.

Greetings,
Sven
Comment 5 Matěj Laitl 2012-10-06 17:29:53 UTC 
Cannot reproduce with current git even if I try hard -> yay fixed! Thanks, Sven.
Comment 6 Sven Brauch 2012-10-06 18:16:58 UTC 
Cool, thanks for your help. :)
