Bug 217744

Application that crashed: konqueror
Version of the application: 4.3.2 (KDE 4.3.2)
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-16-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Copied directory and a file to a network drive (CIFS, mounted via /etc/fstab). Got an error message saying "could not change permissions of file", when clicking the OK button the file manager (both Konqueror and Dolphin) crashes. Have reproduced the bug on two seperate machines.
