SUMMARY kdevelop crashes when moving the "Documents" tool view around the main window. STEPS TO REPRODUCE 1. Open Documents tool view (some file are open and they appear in the view). 2. Drag it from one side of the main window to another. 3. Crash. OBSERVED RESULT Segmentation fault. EXPECTED RESULT KDevelop survives.

Is this reproducible? If it is, could you install debug symbols for KDevelop so we get more details about the functions involved in the libKDevPlatformSublime library? I can't reproduce it here locally (with self-compiled Qt 5.12).
