Frameworks Version: 5.106.0

-- Information about the crash:
Sometimes when you reorder tasks, move out of sub task, put into substask existing ones, application crashes.  Happened to me three times in a row, but I am not sure what causes it specifically, because not every move action triggers it.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: KTimeTracker (ktimetracker), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = <optimized out>}
