Description Panu Kinnari 2009-12-13 11:56:21 UTC

Application that crashed: kget
Version of the application: 2.3.3
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.3
Operating System: Linux 2.6.31-ARCH x86_64

What I was doing when the application crashed:
I had some problems with Kget not redrawing closed details for transfer properly as well as few torrents that wouldn't start download no matter what I clicked.

I removed those to torrent transfers in question and wanted to restart KGet to get rid of mess left by incorrect redrawing of details. And this is when it crashed. I did click "Quit".

Hey!

Are you able to reproduce this bug on KDE 4.4 as well?

Comment 2 Panu Kinnari 2009-12-13 22:41:39 UTC

I have to check when I update. I did't verify that bug is reproducible in current setup either.

Well now that I looked a bit closer at the backtrace:
I think there's no way you can reproduce this bug in 4.4 as all the Observer stuff got removed...

Thanks for reporting anyway :)
