Hi,

In my application the user can choose the location of the KConfig settings
file in the first dialog of the program. He can choose the directory with a
KURLRequester. If I type the path directly in the LineEdit part, all goes ok,
but when I use the directory browser of the KURLRequester to pick the
directory, I get a "SIG41, Real-time event 41" in the debugger when KConfig
does a sync(), even though the dialog with the KURLRequester is already
closed and destroyed. The backtrace is included below.

I am having similar problems with KDirOperator. When I create a file or
directory (in a terminal outside my program) in the directory to which the
KDirOperator is currently set, my program crashes. The backtrace leads to the
Qt event loop, so not much usefull.

If anyone has had similar problems or can tell what I'm doing wrong, thanks a
lot in advance.

Winfried Dobbe

Program received signal SIG41, Real-time event 41.
