Description Raphael Kubo da Costa 2008-09-27 18:15:01 UTC 
Version:           svn r865434 (using Devel)
Compiler:          gcc 4.3.2 
OS:                Linux
Installed from:    Compiled sources

When I open the Acid3 test page (http://acid3.acidtests.org) and have either KIO or the JS debugger enabled in my Java and JavaScript preferences (Settings/Configure Konqueror/Java & JavaScript), Konqueror crashes.

If both are disabled, Konqueror loads the page correctly (and passes 78 tests). The backtrace varies depending on which of the two settings is enabled.

I've attached the two possible backtraces (when both KIO and the debugger are enabled, I get the crash related to the debugger).

Backtrace when the debugger is enabled.
Comment 2 Raphael Kubo da Costa 2008-09-27 18:16:47 UTC 
Created attachment 27593 [details]
Backtrace when KIO is enabled.
Comment 3 Dario Andres 2008-12-06 02:49:31 UTC 
Please, post the backtrace directly (instead of attaching them). It makes it easy to find duplicates. Thanks :)

I also ran into this problem, it work with javascript debugger disabled, but with javascript debugger enabled - konqueror crash, at http://acid3.acidtests.org/
Comment 14 Gérard Talbot (no longer involved) 2011-06-10 14:43:50 UTC 
I confirm the original reporter's (Raphael Kubo da Costa) findings. If JS debugger is enabled (Settings/Configure Konqueror/Java & JavaScript/Javascript tab/Enable debugger), then http://acid3.acidtests.org/ makes Konqueror crash. If JS debugger is disabled, then http://acid3.acidtests.org/ loads and executes (score 89).

Konqueror version: 4.6.4
KDE platform version: 4.6.4
Qt: 4.7.2
Linux 2.6.38-10-generic-pae i686
Kubuntu 11.04 here.

regards, Gérard
