           Summary: kded-obexftpdaemon crashes on adapter removal
    Classification: Unclassified
           Product: kdelibs
           Version: 4.11.60
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: kded
          Assignee: unassigned-bugs at kde.org
          Reporter: woskimi at yahoo.de

Application: kded4 (4.11.60)
KDE Platform Version: 4.11.60
Qt Version: 4.8.5
Operating System: Linux 3.12.0-rc5-mic x86_64

-- Information about the crash:
- What I was doing when the application crashed:

unplugging the BT dongle

I think I should add that I have bluez5 installed. KDE is a very recent 4.12
snapshot from OBS.

The crash can be reproduced every time.
