Bug 202896

Application that crashed: kppp
Version of the application: 2.4.0
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-1-amd64 x86_64
Distribution: Debian GNU/Linux 5.0.2 (lenny)

What I was doing when the application crashed:
To reproduce the bug, start kppp as root, an empty window appears. I add a new method to access my UMTS (3G) USB stick with /dev/ttyUSB0. To define the access details, I then change the tab to enter such, but upon the button click on "new", the sytem hangs. I sent it an FPE, which then allowed to send this bug report.
