are you using bespin style? does it work with oxygen?
Comment 2 Shaun Hunter 2009-12-20 20:25:59 UTC 
I am using bespin. I haven't had a duplicate crash.

Comment 3 Thomas Lübking 2009-12-20 23:31:44 UTC 
this happened on the raster engine and in combination with pseudo widgets (as used by the systray) but should meanwhile be catched (though i'd need the relevant part of the backtrace to really tell)

- which bespin version do you use?

- do you use the raster engine (by default or "-graphicssystem raster" flag) on amarok or (aparently involved) kwallet?

Shaun, Thomas: is this still valid?
Comment 5 Shaun Hunter 2010-01-25 01:01:53 UTC 
I haven't had it happen since the update after I last ripped some CD's.
I'll rip a few to test it and report what I find.

Comment 6 Myriam Schweingruber 2010-02-06 18:23:54 UTC 
Any news on this?
Comment 7 Thomas Lübking 2010-02-06 18:41:09 UTC 
i think you can mark this as closed or outdated or whatever.

since about rev. 600 (mid september 2009) bespin is _really_ picky before calling the winId() function (first checks whether the native widget is really created and has a present winId) so the code path in the backtrace:

#11 0x00007f873e795fcf in QWidget::winId (this=0x1a4f730) at
#10 0x00007f873e795858 in QWidget::create (this=0x1a4f730, window=0,
initializeWindow=<value optimized out>, destroyOldWindow=<value optimized out>)
at kernel/qwidget.cpp:1350

should never occur anymore at all.

I know there was a bug on this (but only reported on the raster graphicssystem) related to a dummywidget used by KSystrayIcon (that classname may be not exact).
The constructor is overridden, doesn't really construct a widget, thus segfaults on ::create() native widget attempts.

Thank you for the feedback.
