Created attachment 112996 [details] the report created with the bug reporting GUI (that failed to send it) - I was only typing code when the attached report was created. - This happens fairly frequently also when I am touching the "Quick Open..." box. I understand kdevelop is, in both cases of typing and touching the "Quick Open..." box, browsing code to find a list of relevant suggestions for completion, so I am suggesting the problem might lie in the code browsing. Possible duplicate of bug 312129 ?

What Qt version is this? Could be https://bugreports.qt.io/browse/QTBUG-64928?
