Bug 282009

Application: kded4 ($Id$)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.3
Operating System: Linux 2.6.40.4-5.fc15.x86_64 x86_64
Distribution: "RFRemix release 15.1 (Lovelock)"

-- Information about the crash:
- What I was doing when the application crashed:
I attached the HUAWEI E1750 3G modem into USB
- Unusual behavior I noticed:
The KDE breaks and nno connection to internet was made.

The crash can be reproduced every time.

-- Backtrace:
Application: Служба KDE (kded4), signal: Segmentation fault
82	T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS)
