iphone tethering over bluetooth is not working after upgrade

[RobertDahlström]

In Lucid my iphone worked flawlessly as a modem over bluetooth. After upgrade it does not seem to be able to connect succesfully.

Attaching the few things that looked relevant in the syslog:

If there is any other way that I can investigate this please suggest it and I will try it. The syslog seems to be polluted a bit by avahi trying ipv6 but I don't know if that is related or not.

I'm also not sure which package this bug belongs too (could be either network or bluetooth related I guess). But since pairing works & the syslog does mention bnep0 it looks like the bluetooth part is working.

With the latest updates everything is working again so there seems to be no need to spend time on this. I'm happy again :)
