works here with the latest blueman, is the bluetooth daemon running?
and edit the title and add blueman
Comment by Ionut Biru (wonder) - Thursday, 20 January 2011, 17:18 GMT
that alone doesn't say anything unless you start debugging properly.

fire up gdb, get a proper backtrace.

I'll add another works for me. So either this has been fixed in the meantime or we are going to need more info to fix. Request reopen if needed.

This error happens in some situations. For me blueman-applet always dumps core when run for the first time (autostarted with the desktop session):

blueman-applet[2790]: segfault at b60b3048 ip b76593d4 sp bf841d74 error 7 in libpython2.7.so.1.0[b75f1000+132000]

but then when I start it manually it works. I have the same package versions as in comment #2, except newer python2:
python2 2.7.1-6

I am using my mouse over bluetooth, so it is critical for me. It did not happen before, but does happen for some time (a guess a few weeks) after package upgrades (I do update packages every few days).

Please don't reopen bug reports unless you have an explicit backtrace of the crash and a meaningful analysis of the problem. Saying "program X crashes" is not a description of a problem.
Comment by Rémy Oudompheng (remyoudompheng) - Friday, 25 February 2011, 22:52 GMT
Also note that finding a segfault in libpython does not necessarily mean that python is broken. It might mean that some binary python module coming with blueman is poorly written/compiled, like the problems we had with pygtk and python 2.7
Comment by Allan McRae (Allan) - Friday, 25 February 2011, 23:51 GMT
This bug report is useless unless we get a back track or even an limit it down to the package upgrade that caused the issue. Multiple people could not replicate on bug day.

this is what it ways when i run it on terminal
   pastbin (8.5 KiB)
Comment by Allan McRae (Allan) - Saturday, 26 February 2011, 02:26 GMT
You will need to run it under gdb to get a backtrace.
Comment by govindarajulu (17.poison) - Saturday, 26 February 2011, 03:29 GMT
blueman-applet is written in python.
how do u run it in gdb?
Comment by Allan McRae (Allan) - Saturday, 26 February 2011, 05:42 GMT
gdb python2
run /usr/bin/blueman-applet
Comment by govindarajulu (17.poison) - Saturday, 26 February 2011, 07:53 GMT

Try:

Change line 173 of
/usr/lib/python2.6/site-packages/blueman/main/PulseAudioUtils.py
from
pythonapi.Py_DecRef(data)
to
pythonapi.Py_DecRef(py_object(data))

i guess we can close this bug report!
Comment by Allan McRae (Allan) - Saturday, 26 February 2011, 08:17 GMT
@ioni: according to the Fedora bug report, that fix has been approved by the upstream dev. So you can rebuild away! :P
