           Summary: crash with gpsd not running
           Product: marble
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: marble-bugs at kde.org
        ReportedBy: anders at alweb.dk


Version:           unspecified (using KDE 4.7.3) 
OS:                Linux

I experience a crash after having turned current location on, using gpsd.
After stopping gpsd, marble crashes at start, with the below trace.

The crash does not happen if I remove a line defining gpsd as the active
position provider from marblerc.

I also observed that marble does not react when gpsd is stopped, or the gps
device removed, it keeps showing the position icon.

1. start marble, start gpsd and add a device
2. remove the device and stop gpsd
3. close marble
4. start marble => CRASH

Actual Results:  
well, crash

Expected Results:  
no crash
