Your contribution for this not yet stable application can be very usefull.
If you want to able to report a bug compile KSniffer as follows:

./configure --enable-debug=full
make
su -c "make install"


If you want to report a crash you could run it as:

ksniffer --nofork


Thank you for your report.
The application is under development than try to report bug via e-mail just
after you updated with the last available KSniffer version and you get the same
crash.
