Description Enrico Bandiello 2009-10-03 14:11:36 UTC

Application that crashed: amarok
Version of the application: 2.2.0
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.31.1 x86_64
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
Amarok complained about missing "kwallet" and asked to save last.fm password in a plain text file. The whole application crashed just after choosing "yes"

 -- Backtrace:
Application: Amarok (amarok), signal: Aborted

Comment 1 Mikko C. 2009-10-03 14:17:43 UTC

bakctrace indicates a crash in kdelibs:
#10 0x00007f64506192fd in KShortcutsDialog::~KShortcutsDialog() () from
/usr/lib/libkdeui.so.5

Possibly the same as bug #196207

Comment 2 Christoph Feck 2009-10-03 17:16:50 UTC

Looks like malloc & friends are not thread safe?

Comment 3 Dario Andres 2009-10-03 18:33:14 UTC

@Enrico: are you using QtCurve as Qt4/KDE4 widget style ?
Thanks

Comment 4 Enrico Bandiello 2009-10-03 18:47:03 UTC

@Dario: yes, I do.

Comment 5 Dario Andres 2009-10-03 18:50:28 UTC

Bug 198947 has a similar backtrace and it is also a bug caused by QtCurve (I don't know if the maintainer was informed about it...)
Switching to another style should workaround the crash until it is properly fixed. - Could you check this ? Thanks

Comment 6 Enrico Bandiello 2009-10-03 19:00:06 UTC

@Dario: I just tried to start Amarok again, with QtCurve as widget style, and it started up beautifully and with no complaints.

Comment 7 Dario Andres 2009-10-03 19:01:26 UTC

It may be a corner-case then...
Thanks
