SUMMARY

While searching in QuickOpen, shortly after loading a session containing the KDevelop source, KDevelop crashed with the backtrace below.

I wasn't able to reproduce this by repeating a similar sequence of actions.

SOFTWARE/OS VERSIONS
KDevelop 5.6-git bd8a49a10a (5.5.80 plus a few patches since).
Arch Linux
KF 5.73.0
Qt 5.15.0
