           Summary: kded4 uses 100% of core on mobile broadband modem
                    disconnect
           Product: kde
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: crispin at caverock.net.nz


Version:           unspecified (using KDE 4.6.2) 
OS:                Linux

kded4 uses 100% of core on mobile broadband modem disconnect (Kubuntu 11.04).
Using sakis3g to connect as Network manager applet will not connect Vodafone
Huawei modem.
2 kded4 processes are found to be running in system activity.
Some processes won't start or are seriously delayed (amarok / logout) -
sometimes system becomes sluggish.
On killing kded4 process, system is returned to normal.

Reproducible: Sometimes

Steps to Reproduce:
Disconnect mobile broadband modem.

Actual Results:  
System Activity shows 100% cpu usage for kded4

Expected Results:  
CPU should idle

Network Manager applet removed, as it will not connect vodem, and interferes
with Sakis3g.
I also seem to be experiencing the same symptoms intermittently without
connecting to the internet, with kded4 and knotify4 using 100% of one core.
