Bug Description

I can not use mobile phone as modem through bluetooth using PAN ("Network Access Point" in context menu in blueman) in blueman. If in "Local Services" I choose using Network Manager, when I try to connect, blueman writes:

    conns = self.nma.ListConnections()

If I don't use NM, there is connection "bnep0", but it is not configured. If I can turn off this connection in Blueman, Blueman hungs.

In Ubuntu 11.04 it had worked. I tried to install previous version of blueman from Natty repositories and newer (1.23) version from ppa. But there is some trouble with these versions.

The crash happens as soon as the Ihpone ( 3GS ) paires .
I have deletet the units on both sides, restart the PC, restart the Iphone and repairing again in order to find out which part of the bluetoth SW causes the crash.
Most of the cases it is the blueman-manager but as in this case the aplet

This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '12'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 12's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 12 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:

Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.

Why nobody answers (not only on this site)? Is this problem affect only me? Or nobody uses telephone as modem via Bluetooth?

No useful input from me i'm afraid, just that Debian Wheezy seems to exhibit the exact same problem.

Including it here on the chance that someone there works out what the problem is

initialize self.nma and self.nm as they are on watch_name_owner events Edit (931 bytes, text/plain)

Here's a patch that worked for me. It adds some lines to what becomes /usr/share/pyshared/blueman/plugins/applet/NMPANSupport.py during installation, to set up variables that are otherwise left initialized to 'None', hence the error when they're used later on.

Note that I don't know anything about DBus, have barely glimpsed at Python prior to this, and in particular have no knowledge of how Blueman's developer intended for things to work, so apply at your own risk.

Come on! Why this is not in the newest Xubuntu? I upgraded whole system just to get this repaired. It is so annoying that I can't use tethering with my phone only because of this little bug and releasing it's fix takes ages!
