Application that crashed: kcmshell4
Version of the application: 
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.31-gentoo-r3 i686

What I was doing when the application crashed:
I had recompiled libgphoto2 to include support for all cameras.   I then plugged in my Sony Ericssion C905 via USB, and started Kamera.  I clicked on Add, selected my camera model in the dialog, pressed enter, where it added it to the list.  When I clicked or ctrl-clicked (so that the below-mentioned camera stays selected) on "USB PTP Class Camera" and clicked Remove, kamera crashed.

My libgphoto2 is 2.4.7.
