Description Alex Fiestas 2012-04-23 15:12:02 UTC

This crash happened to me at least 5 times (I have 5 .kcrash in my crash folder) so it is quite reproducible.

I was basically writting code when this happens.

Reproducible: Always

Comment 2 Milian Wolff 2012-04-25 13:02:54 UTC

if it's reproducible, run kdevelop in valgrind and figure out whats crashing there, esp. whether m_view is still valid. If not, try to wrap it locally in a QWeakPointer and check whether that helps.

but a proper way to reproduce this would be helpful!

fix crash in signature assistant when view gets closed before parse update

the question remains whether we might not want to delete the assistant before
the view anyways, similar to how we do it with the rename assistant
