syncdaemon does not get started by client-applet after relogging (stalled lock file)

[Rick McBride]

after having tested the new client for a bit, I decided to relog. While the client applet starts, it doesn't indicate a connection, and selecting "connect" doesn't help (interestingly the icon itself looks normal and doesn't have the red X for a disconnected state.).

ps aux|grep ubuntuone shows that syncdaemon isn't running.

I let things idle for a bit, and then started syncdaemon manually.

It appears to crash.

I'll attach the apport-collect

EDIT: Looks like this is related to the new "don't run more than one syncdaemon on an account" code.

The fixes to the lock aren't enough.
We talked on IRC< that we'r going to remove NFS mounted home support and use DBus to detect of a daemon instance is already running.
