Comment 1 A. Spehr 2009-04-05 12:39:16 UTC 
Do you know what you were looking at when that happened? (url, etc) Can you reproduce it consistently? Can you tell us any more about how to reproduce the crash?

If you follow the instructions here, you can load debug symbols and give us a better backtrace:

Thanks!
Comment 2 Miroslav Ľos 2009-05-01 23:19:54 UTC 
I have a very similar backtrace with debug info here. Sadly, I do not remember where exactly I had been when it happened, and was unable to reproduce it on any recently visited site. As you can see, I was closing konqueror at the time.
And bug #190712 really seems to be the same thing as ours.
