Each time I login to Kubuntu 15.10 the loading bar takes almost exactly 31 seconds until the fade effect to the desktop. Note that this is not the bug with bluetooth where the desktop would be scambled and took long to load (I had that as well, has already been fixed).

I measured how long the login takes a couple of times and it always was around 31 secs. After 4 seconds, the bar is at ~80%, after anotehr 4 secs it's at 100% and it stays there for around 23 seconds until it transitions to desktop. I assume that something is waiting for a timeout but I have no clue what causes this.

Using other users had no effect, I even created new ones with the same result. It happens each time I login, not just after cold start or reboot. I can only lock/unlock the desktop without problems.

I tried system-analyze blame but I think that happens before login
