Application: konqueror (4.9.3)
KDE Platform Version: 4.9.3
Qt Version: 4.8.4
Operating System: Linux 3.6.9-2.fc17.x86_64 x86_64
Distribution: "Fedora release 17 (Beefy Miracle)"

-- Information about the crash:
- What I was doing when the application crashed:

Mainly to see what would happen :) I extracted the Billion Laughs xml from http://en.wikipedia.org/wiki/Billion_laughs and put it in a file and called
/tmp/billion.xml and ran:

    konqueror /tmp/billion.xml

konqueror opened up the window and then sat chewing CPU for quite a while and finally keeled over.  At the time it died, its RSS had reached 2.1GB.

This is a fairly well-known DoS attack and presumably could be triggered by visiting a suitably malicious web site.

-- Backtrace:
Application: Konqueror (konqueror), signal: Aborted
