           Summary: 3G modem error
           Product: kdelibs
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: kded
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: jonathan_hepp at yahoo.com.br


Application: kded4 ($Id$)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Accesssing the internet. The 3G modem was disconnected by itself and then the
system crashed.

- Unusual behavior I noticed:
The Network Manager refused the 3G internet modem and restart the system was
needed.

The crash can be reproduced every time.

-- Backtrace:
