Comment 1 Dario Andres 2010-12-15 15:04:30 UTC

[Comment from a bug triager]
The crash is related to a font issue (and may be the Qt library)
- Is this still happening with an updated KDE SC and Qt 4.7.x ?
- Which sites were crashing Konqueror ?
- Did you have some unusual font settings ?
Regards

Comment 2 Stephen McIntosh 2010-12-16 01:26:49 UTC

Yes it is, well maybe even worse, sometimes my computer freezes when I am using Konqueror, especially when I just leave my computer. It never freezes my computer when I am using Konqueror. Well this should be added as a new bug, so... Anyways, no it doesn't anymore. No, I have none, just the default.

*** Bug 267226 has been marked as a duplicate of this bug. ***

Comment 4 Christophe Marin 2011-02-27 10:56:21 UTC

from bug 267226

-- Information about the crash:
- What I was doing when the application crashed:
just browsing some page in subscribed RSS. It just happens once a day or so.

I think it may be related to bug 215258.

The crash can be reproduced some of the time.

Comment 5 Marcin Gryszkalis 2011-03-07 01:26:08 UTC

Created attachment 57735 [details]
New crash information added by DrKonqi

akregator (1.6.6) on KDE Platform 4.6.00 (4.6.0) using Qt 4.7.2

- What I was doing when the application crashed: Opening article. Note that I reported same problem before (marked as duplicate) and I switched to standard KHTML backend after many crashed with WebKit backend - now I'm getting crash again.

Comment 6 Dawit Alemayehu 2011-06-20 04:20:54 UTC

My distro is also ArchLinux, but I cannot reproduce this issue in either one of the rendering engines. Perhaps there is some sort of font cache corrpution on your systems ? Have you tried to remove the font cache located in your home directory ?

Comment 7 Stephen McIntosh 2011-06-21 15:42:20 UTC

It's fixed.
