Attachment: Logs of device crash after unpairing

Description:
If the user is in a Bluetooth session and the other user unpairs after the user fails to send two files at once, the user's device will crash and restart.

Repro Steps:
1) Updated to Unagi Build ID: 20130411070205
2) Pair the device with another user's device.
3) Launch the Music app and send a music file (the larger the better).
4) Have the other user accept the transfer.
5) While the file is transferring, attempt to transfer another file.
6) Cancel the transfer in progress.
7) Have the other user unpair from the device.
8) Observe the device's reaction.

Actual:
A few seconds after the other user unpairs, the user's device will restart then report that the OS has crashed.

Expected:
The users' devices are unpaired with no errors.

Device crashes when transferring multiple files simultaneously. It is expected while one file is in transit, the remaining files would be spooled for transmission afterwards.

Couldn't find anything from the attached log. I'll try to take a look next Monday, shouldn't be so hard to reproduce since it's 100% reproducible.

I was unable to repro using the exact steps in Unagi version 20130412070204.  However, I was able to get it to crash on an attempt to transfer a file to another device.  The URL for the crash report is https://crash-stats.mozilla.com/report/index/33a6605f-c00a-498f-95db-521a02130412

The crash is a known issue. Please see bug 860075 for more information.

Since the reporter, QA and me couldn't reproduce on the latest build, close this bug as WFM.
