Hi,
Testing from Bill Kenworthy indicates that commit 0a85b964e141a4b8db6eaf500ceace12f8f52f93 introduces a ppp-over-bluetooth regression.

I see this has already been reported by Johannes Hoerhan on the bluez list. http://thread.gmane.org/gmane.linux.bluez.devel/10148/focus=10232
I don't really see how this could be a udev issue, since it's obviously so intricately linked to that line of code.
How can we help diagnose this further - any debugging flags we should turn on?
