Application: konsole (15.04.0)

Operating System: Linux 4.1.6-200.fc22.x86_64 x86_64

-- Information about the crash:
- What I was doing when the application crashed:
I closed the Konsole window. 
Prior to closing, I opened it with the shortcut "Control+Alt+t", used keychain to add my ssh-keys to the agent, then connected via ssh to a remote machine, worked for a while (less than a few hours). Then, I exited my work session by typing exit in the ssh session and then exit again on the local session.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konsole (konsole), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
