Comment 1 Kevin Funk 2018-11-19 19:43:55 UTC 
For the record: Can't reproduce with my debug build. 

Is this reproducible and can you provide a minimal working example?
Comment 2 Rolf Eike Beer 2018-11-21 20:06:15 UTC 
It looks like I can trigger that basically every time I call "update signature" from a tooltip. The background parser was not running the last times I tried (at least there was no related progress bar), and I used a different project (KGpg in this case) as test.
