That doesn't look like a bug in KDevelop; either in KTextEditor or Qt. Either way, please install the debug symbols for KTextEditor next time you hit this issue, so we can see line numbers in the backtrace.

New crash information added by DrKonqi

kdevelop (5.9.220770 (22.07.70)) using Qt 5.15.2

When I click at the line end, sometimes KDevelop will crash.
