Bug 231470

Application that crashed: kbluetooth
Version of the application: 0.4
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.12-desktop-1mnb x86_64
Distribution: "Mandriva Linux 2010.0"

What I was doing when the application crashed:
There are several problems here. First, when initiating an obex file transfer from my PC to my mobile device, I notice that TWO file transfer jobs are triggered...my file is being transfered twice. The situation becomes even stranger when I select multiple files to transfer...some of the files don't get transfered (in my case, every other file was successfully transfered...e.g., file 2, file 4, file 6...).

When the last file in the set was reached, the transfer job appeared to be hung, at 0% complete. After a while, I decided that it was never going to finish, so I clicked the "stop" button on the job notification. This is when kbluetooth crashed.

Considering the other bugs related to crashes in doKill, the crash may be a duplicate of the other bugs. But the situation that led me to kill the job in the first place also needs to be investigated.
