            Bug ID: 327765
           Summary: Bluetooth crashes when other devicew attempts to pair
    Classification: Unclassified
           Product: kdelibs
           Version: 4.11.2
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: kded
          Assignee: unassigned-bugs at kde.org
          Reporter: danielnez1 at gmail.com

Application: kded4 (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.5
Operating System: Linux 3.11.6-4-desktop x86_64
Distribution: "openSUSE 13.1 (Bottle) (x86_64)"

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

I am attempting to send a file via a Mac using Bluetooth. When I set Bluetooth
to be visible on my laptop running KDE, the laptop is listed on the OSX file
transfer application. However when trying to pair, the OS X file transfer
application displays the pin code and on KDE KWallet briefly appears in the
system tray and immediately after I get a segmentation fault.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Dæmon (kded4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
