Qt Version: 4.5.3
Operating System: Linux 2.6.32-trunk-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
used konqueror to check if my nfs exported folder was appearing in the Network section of konqueror. As soon as a attempted to expand the server node (my own system), konqueror crashed.
