Crash backtrace

Konqueror crashes when switching to or open new tab. I failed to figure out any correlation between url being open and crashes, but at the moment I have a relatively short sequence that repeatedly crash each time it is followed:
1. Start konqueror
2. gg:connector_1_5.xsd
3. Ctrl+click 1st link (http://java.sun.com/xml/ns/j2ee/connector_1_5.xsd) to open it in a new tab (background), switch to it via tab click and let it load
4. It opens the xsd file using katepart
5. Ctrl+T to open a new tab
6. It crashes.

I use khtml as default web engine, but it crashes the very same way with webkit one. I'm not absolutely sure, but it is very probable that all (ta least most) of those numerous crashes I had were when it was tab with non-html content (an image link or text document as in the sequence described)

The trouble still persists with kde 4.8.2. The backtrace above is of crash occured after the following:
1. Open https://bugs.kde.org/buglist.cgi?query_format=advanced&short_desc_type=allwordssubstr&short_desc=&long_desc_type=substring&long_desc=&bug_file_loc_type=allwordssubstr&bug_file_loc=&keywords_type=allwords&keywords=&bug_status=RESOLVED&bug_status=VERIFIED&bug_status=CLOSED&emailtype1=substring&email1=&emailassigned_to2=1&emailreporter2=1&emailcc2=1&emailtype2=substring&email2=&bugidtype=include&bug_id=&votes=&chfieldfrom=2011-06-01&chfieldto=Now&chfield=cf_versionfixedin&chfieldvalue=4.8.2&cmdtype=doit&order=Bug+Number&field0-0-0=noop&type0-0-0=noop&value0-0-0=
It is the link from 4.8.2 announce on kde.org
2. Open a new tab
3. It crashed

Comment 3 Alex 2012-04-05 12:01:13 UTC

I found how to stop it from crashing. I had hotkeys assigned for webkit/khtml view mode switching. If these assignments removed it doesn't crash anymore. If either webkit or khtml view mode has a hotkey assigned it crashes as reported above. Hotkey has not to be used in order for it to crash, it just has to be assigned

Comment 5 Dawit Alemayehu 2012-09-25 05:41:04 UTC

Unfortunately since ArchLinux does not provide any debug packages, the backtrace provided is completely useless. :(

However. I think this bug report is effectively the same as the one reported in bug# 299020. See the last few comments of that bug report.
