Can't reproduce it myself on current git master.
*** Bug 499382 has been marked as a duplicate of this bug. ***
Can't reproduce. Tried different ways to reproduce the bug: 1. Suggested in the bug report 2. Create new GPT table and unplug. 3. Create different file systems and unplug. 4. Import Partition table and then unplug.
Errr... I see a related crash (#499382) in 6.2.5.
Apparently not fixed yet, as we have a new report (bug 494659) from Plasma 6.2.5 with the same backtrace. Re-opening.
