[Pkg-utopia-maintainers] Bug#905171: Subject: network-manager: Network-manager will not connect to known wifi networks "no secrets provided"

[Jon Westgate]

Package: network-manager
Version: 1.12.2-1
Severity: important

Dear Maintainer,

Since upgrading from NM version 1.10.x I've noticed that it is getting 
increasingly hard to connect to wifi networks.
With version 1.11.x you couldn't switch networks without first 
disconnecting. That was not ideal but I could deal with it.
Version 1.12.x is just unusable it just tells me "No secrets provided" 
and or "No Agents were available for this request"
I'm running KDE so using the plasma UI. If I just downgrade to 1.10.x 
everything just works again wifi automaticly connects as soon as dpkg 
has finished.
Is there something silly that needs doing like purging settings that 
will fix this? The annoying thing about downgrading is that it means I 
can't use PPP and therefore
most VPN's are unavailable to me.
