Version:           unknown (using KDE 3.3.0, compiled sources)
Compiler:          gcc version 3.2.3
OS:                SunOS (sun4u) release 5.8

In any KDE application that provides the file browser, the
moment I start typing into the location text field, the app
dies with a bus error trying to complete the file name.

Please note that completion works fine in konqueror for web
addresses. It is only the file completion that is problematic.

Here's the stack trace:

Any clue as to what I am doing wrong?

Thanks,
