Attachments: Valgrind log of Konqueror crash

Description Morten Bo Johansen 2008-09-15 13:17:42 UTC
Version:            (using KDE 4.1.1)
OS:                Linux
Installed from:    Debian testing/unstable Packages

This is hard to reproduce and thus hard to describe more precisely in the short description, but Konqueror crashed upon opening a page in a new tab. I restored the session but I could not reproduce it. Plugins are disabled whereas java and javascript are enabled. Backtrace follows:

Application: Konqueror (konqueror), signal SIGSEGV

Comment 1 Morten Bo Johansen 2008-09-15 13:18:49 UTC
KDE 4:4.1 packages are from Debian's experimental repository
Comment 2 Frank Reininghaus 2008-09-15 21:37:30 UTC
Thanks for the bug report. If you manage to reproduce this crash and are able to provide step-by-step instructions to crash Konqueror (e.g., go to some URL, click a link, ...), please add them to this report. Judging by the backtrace, this looks like a duplicate of bug 162564, but maybe some other test site is easier to analyse.
Comment 3 Morten Bo Johansen 2008-09-23 14:05:26 UTC
Here is a page that will reproduce the crash, please try to open this page:

http://derstandard.at/?url=/?id=1220458830719

and the crash occurs. It has nothing to do with tabs btw.

You may want to do this quickly as it is a news article that may be obsoleted soon.
Comment 4 Morten Bo Johansen 2008-09-24 20:27:56 UTC
Created attachment 27554 [details]
Valgrind log of Konqueror crash

Here is an additional log from valgrind. Hopefully useful.
Comment 5 Frank Reininghaus 2008-09-30 00:17:38 UTC
Thanks for the update. A few days ago I got a crash with the test URL, but now neither 4.1.1 nor today's trunk crash for me. I had tried to download the page to be able to analyse it, but these derstandard.at pages are hard to get hold of :-(

Crashes on derstadard.at have been reported a few times, see bug 165601. I'm not sure though if those reports are somehow related to this one, the backtraces look different.
