Description Dennis Schridde 2013-03-10 18:56:32 UTC 
Application: ktp-text-ui (0.5.80)
KDE Platform Version: 4.10.1
Qt Version: 4.8.4
Operating System: Linux 3.8.2-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
- What I was doing when the application crashed:

A conversation was open with only a few messages exchanged. I then was using another program, after which I alt-tabbed back to the conversation window. Soon after I started typing another message, ktp-text-ui crashed.

-- Backtrace:
Application: Telepathy-Text-Oberfläche (ktp-text-ui), signal: Segmentation fault

We found out what's wrong, fix is no the go
Comment 5 Martin Klapetek 2013-03-13 16:53:03 UTC 
Found how to reproduce the bug, and the cuase.

[15:00] <d_ed> jtalk: ok, imagine you have the setting "open tabs in a new
window'
[15:00] <d_ed> you open window 1
[15:00] <d_ed> it gets the right action, things are good
[15:00] <d_ed> you open window 2
[15:00] <d_ed> you get the action for the first window
[15:00] <d_ed> things still work
[15:00] <d_ed> you close window 1
[15:00] <d_ed> that KAction* is now deleted
[15:00] <d_ed> you type in window 2.. crash

Git commit c971c72970192ab6bd2df246fa53c44028ff0093 by Roman Nazarenko.
Committed on 13/03/2013 at 18:47.
Pushed by romann into branch 'master'.

Fixed crash on Send Message shortcut checking, when tab was detached and parent window was already destroyed.
KAction pointer is replaced with KShortcut object inside every tab's Text Edit.
