This bug is in no way related to kdevelop-python. Please report it to the Python bugtracker.
Comment 5 Sven Brauch 2014-03-22 19:20:17 UTC 
... or more likely the PyQt bugtracker, looking at the backtrace again.
Comment 6 Simon Andric 2014-03-22 23:03:06 UTC 
hello!

thank you for your kind reply...ay i just ask - where can i report pyqt bugs? i dint find anything corresponding to that here on bugs.kde.org - although dr. konqi persists to file the bug under thiw webpage...

thank you


Simon :)
Comment 7 Simon Andric 2014-03-22 23:16:32 UTC

https://bugs.launchpad.net/apport/+bug/1296161

i hope it is the right place...

thank you

Comment 8 Sven Brauch 2014-03-23 10:43:32 UTC 
I don't know, could be multiple components at fault here, Apport, PyQt, Qt, or Python -- in this order of likeliness. You'll have to investiagate / ask around. The project's bug trackers are certainly easy to find with the search engine of your choice, I don't have the links handy.

P.S.: You're aware that an email is sent to ~10 people each time you comment or change a bug? So please feel free to add comments when there's new information but try to avoid splitting information across five posts.
