Description alsaf 2010-11-24 22:16:13 UTC 
Application: parley (0.9.4)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-23-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
I use Parley for a practise session which it works ok and then I exit from it. The crash always occurs when I go back into Parley afterwards and try to start practice mode by going into Practice menu then selecting Practice option.

The crash can be reproduced every time.

-- Backtrace:
Application: Parley (parley), signal: Segmentation fault

Comment 1 alsaf 2010-12-08 22:20:22 UTC 
The 'bug' seems to have been fixed by having at least of the toolbars shown (I have Statistic toolbar ticked without the error happening)
Comment 2 Dario Andres 2010-12-12 15:34:11 UTC 
[Comment from a bug triager]
The backtrace looks related to the one in bug 256292 (bug 220004), which seems to be a bug in the Qt library.

Comment 4 Marius 2010-12-27 17:39:32 UTC 
I can confirm that Parley crashes when trying to enter Practice mode from the menu. It crashes also when one or more toolbars are shown. I am using Parley-0.9.4, kdelibs-4.5.4 and Qt-4.7.1. My Backtrace looks a little bit different:

Hi,
Given that we were several to find the same bug (see the duplicate tickets), maybe this should be tagged as CONFIRMED ?
Comment 13 Marius 2011-09-22 21:42:47 UTC 
Klipper, as stated above, seems to face the same issue (Bug 220004), and also Kontact (Bug 218310).
