Bug 67737

Version:            (using KDE KDE 3.1.93)
Installed from:    Compiled From Sources

In some applications, the file open dialog crashes on accessing a device through the kio devices protocol. Some applications that do crash:
JuK, Find Files
And some applications that don't:
kwrite, konqueror, kate
The application crashes when I do the following: I open the application, and open the Open File dialog (or equivalent), and go to the devices directory using the shortcut on the left. I click on a mounted device (in my case the hard disk hdd8) and *poof* the application is gone. Clicking on an unmounted device (my CD-Rom is the only unmounted device) disk doesn't seem to crash. Unfortunately I can't tell whether it crashes after the mounting, because my user isn't allowed to do that (I could change that if that would be required to track this down).

The backtrace from the crash handler:

Unfortunately no line numbers, sorry for that. I hope this provides enough information to track this crash down.

PS: Since it seems to crash explicitly on the devices protocol, I placed the report here.
