Comment 1 Dario Andres 2009-12-31 16:11:48 UTC

Mh, I can't reproduce even when I enabled the JS Debugger and the "report errors" option. Here using:

Qt: 4.6.0 (kde-qt master commit 747ff8e6ef6f5a1163dfa75bc9ac4755ce7083d1
        Date:   Tue Dec 15 11:58:13 2009 +0100)
KDE Development Platform: 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2))
kdelibs svn rev. 1067378 / kdebase svn rev. 1067378
on ArchLinux i686 - Kernel 2.6.31.6

- Can you still reproduce with an updated build ? Thanks

Comment 2 David Palacio 2010-01-01 21:19:00 UTC

Qt: 4.6.0
Plataforma de desarrollo de KDE: 4.3.86 (KDE 4.3.86 (KDE 4.4 >= 20091231))

Still crashes on updated build. Same backtrace.

Try to disable javascript and whitelist www.kde-apps.org.
Global options:
no debugger, no error report
Open new windows set to intelligent
Resize, move, focus window; modify status bar text: Ignore

Comment 3 David Faure 2010-02-25 15:04:04 UTC

Fixed for 4.4.1.
