Description Rafael 2011-10-22 17:28:10 UTC
Version:           unspecified (using KDE 4.7.2) 
OS:                Linux

Using OpenSUSE 12.1 RC1 with KDE 4.7.2 and Bluedevil 1.2.1.
When I try to browse a mobile phone via bluetooth with Dolphin, kded and
plasma-desktop, both crash, and the files in the mobile phone are never showed.
I am unable to browse a bluetooth device at this moment.


Reproducible: Always

Steps to Reproduce:
1. Install OpenSUSE 12.1 RC1 with KDE.
2. Asociate a bluetooth mobile phone using Bluedevil.
3. Try to browse the mobile phone via Dolphin bluetooth service.
4. Kded and plasma-desktop crash and the device is not browsed.

Actual Results:  
Kded and plasma-desktop crash and the device is not browsed.

Expected Results:  
The bluetooth device should be correctly browsed and plasma-desktop and kaded
should never crash.

The following are the two backtraces.

Comment 2 Lamarque V. Souza 2011-10-23 19:40:01 UTC
Sorry, this bug is not closed yet. As you can see in the crashlog there are two crashes. I fixed the crash in Plasma NM, now the Bluedevil's guys need to fix the other crash. Changing the component to bluetooth-daemon.
Comment 3 Will Stephenson 2011-10-27 11:26:37 UTC
Not fixed in 1.2.2 or by 0a733a50 .  Relevant valgrind details at: https://bugzilla.novell.com/show_bug.cgi?id=725962
Comment 4 Will Stephenson 2011-10-27 11:28:03 UTC
The valgrind trace shows it's a double delete.  There is no second bluetoothd session happening, so it is not the same as bug 269814.
Comment 5 Will Stephenson 2011-10-27 16:53:28 UTC
Not a double delete but using the value of a const_iterator after it has been removed from its QHash (ie invalid)

Fixed by ef94eedf (1.2 branch) and ae22e934 (master)

Comment 8 Lamarque V. Souza 2011-11-05 00:17:07 UTC
I still see kded4 crashing when turning my bluetooth controller off even after updating Bluedevil to the latest git version.
