Application: konqueror (4.7.4 (4.7.4))
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.1.9-1.4-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I was attempting to do the steps listed in bug 186731, but Konqueror crashed when it was trying to load the page. Konqueror crashes about 50% of the time when I follow the steps detailed below.
If you see a blue banner along the top of the website, then Konqueror has already passed the point where it might have crashed following these steps.
The steps I followed are:
1. Go to https://bugs.kde.org/show_bug.cgi?id=186731 in Firefox
2. Start Konqueror
3. Copy "http://bazaar-vcs.org/Documentation" from the page opened in step #1
4. Paste it into Konqueror with a click of the mouse wheel.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
