Description René van Buuren 2016-12-11 14:04:52 UTC 
Application: konsole (16.08.3)

Qt Version: 5.7.0
Frameworks Version: 5.28.0
Operating System: Linux 4.4.0-53-generic x86_64
Distribution: KDE neon User Edition 5.8

-- Information about the crash:
- Custom settings of the application:
I use Konsole profiles that are set to launch autossh to connect to a particular server.

- What I was doing when the application crashed:
Whenever I try to close a tab that was launched with one of these autossh profiles, Konsole crashes in its entirety, killing the window with all tabs inside of it, including local ones that had nothing to do with autossh.

(This problem does not occur when I change autossh to regular ssh in the profiles, but I depend on the measures autossh takes in the background to avoid connections getting dropped and to reopen them when they do.)

The crash can be reproduced every time.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault

I'd be interested if you still have issues w/ a newer release - a number of bugs were fixed in 16.12.x and later

I'm now on 16.12.2, and this does seem to have been fixed. Konsole now gives the appropriate warning about killing autossh and no longer crashes. Thanks :)
