Description Baptiste Mille-Mathias 2010-03-31 14:11:14 UTC 
It seems a crasher appears in 2.30 when one disable bluetooth.
I don't have a valgrind log for now but trying to get one at https://bugs.edge.launchpad.net/bug/552140

for now I have only the stacktrace (http://launchpadlibrarian.net/42565560/Stacktrace.txt)

I try to get back with the needed material asap.

Bug isn't readable downstream, and the valgrind traces are missing debuginfo for gnome-bluetooth.

This is most likely wrong:

right the issue is a distro one, we don't have specific change but backported the leak fix from git some time ago and didn't drop it with the update, it still success to apply but duplicate the g_free too , I'm fixing that now...

The patch you shipped was not sent upstream, and I had to go fish it out of the Ubuntu packages. Not nice.
