confirmed, yet again. i thought that rather than make a 20th report of this same, still "unconfirmed" problem, i'd just pile on here. can it be looked at soon?

trace (i don't appear to get the option of reporting this automatically):

Comment 2 Daniel Boles 2015-12-22 00:50:43 UTC

oh, should've said: for me this happens every time Konsole is closed: simply open a window, do absolutely nothing, then close using your choice of "exit" or the GUI button or the File menu. Each time, same result

Comment 3 Daniel Boles 2016-01-11 21:11:45 UTC

For me, some intervening update seems to have fixed this. Konsole hasn't been updated since version "konsole:amd64 (15.08.2-1, 15.08.3-1)" on the 12th, before I confirmed the bug, but now it does not crash on exit.

Hopefully this has fixed it for other users with this problem, too?
