Report to https://bugs.kde.org/

Reproducible: Always

Steps to Reproduce:
1. I'm on virtualbox, using kubuntu 13.10beta1
2. I have it set up with apcio... and two cpus.. donno if that matters, and I have a few other hardware acceleration options enabled.
3. click on touchpad within the mouse module
Actual Results:  
crash

Expected Results:  
if it really is a downstream problem, there should be a message telling me that there is a known bug with synoptics drivers, and give me the contact information for them.

It should also not crash the whole program.

Handle crashes well.
