-- Information about the crash:
This seems to have already been reported. I'm reporting in case the backtrace may add useful information to find the issue and help solve it.

Kdevelop crashes frequently when I delete a folder from the project view.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
