Description Viktor Erdélyi 2009-03-18 20:53:04 UTC

Version:           4.2.1 (?) (using KDE 4.2.1)
OS:                Linux
Installed from:    Fedora RPMs

I started it, it started in the tray. When I wanted to see the window, it crashed:

QWidget::insertAction: Attempt to insert null action
QWidget::insertAction: Attempt to insert null action
kget(17008) KDynamicJobTracker::unregisterJob: Tried to unregister a kio job that hasn't been registered.
KCrash: Application 'kget' crashing...
sock_file=/home/user/.kde/socket-sierravista.nyetwork/kdeinit4__0

(the above info is what I got when starting it from the console)

Please attach a backtrace...: http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

Thanks

Lukas

Comment 2 Viktor Erdélyi 2009-03-19 22:22:38 UTC

Here you are. I don't know why it says it isn't useful, it's much better than the previous "no debug symbols found" messages. Thanks for the link btw.

==========================================================
This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.

Comment 3 Viktor Erdélyi 2009-03-19 22:31:35 UTC

Another one from gdb (looking at this, I'm seriously considering an update of my Qt 4.5 rpms)

Comment 4 Marco Martin 2009-03-19 22:44:41 UTC

it's a problem of the polyester widget style, so not kde one
however i would be happy of a backtrace with the polyester debug symbols installed too :D

Comment 5 Viktor Erdélyi 2009-03-19 22:51:59 UTC

Right, Polyester, I just found it too... here is the backtrace.

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7ffff63fd800 (LWP 5937)]
PolyesterStyle::subElementRect (this=0x71d810, se=QStyle::SE_ProgressBarGroove, option=0x7fffffffa3b0, widget=0x0)
    at /usr/src/debug/polyester-1.9.0/style/polyester.cpp:3609
3609              return QRect(widget->rect());

With other styles, it's ok. With polyester, it crashes IF it has a download running.

PS: I can't find a place to report this for Polyester developers...

Comment 6 Viktor Erdélyi 2009-03-19 22:57:05 UTC

Some more lines of it:

Comment 7 Marco Martin 2009-03-20 10:10:29 UTC

Viktor: that problem is solved in the last released version

Comment 8 Viktor Erdélyi 2009-03-21 14:40:34 UTC

What is the last released version? (and where can I get it)
