Comment 5 for bug 884651

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.
