Activation of org.freedesktop.UDisks2 timed out

[Michael Heuberger]

I am unable to manage my disks. When I try so via command line I get this timeout error

$ gnome-disks
(gnome-disks:4229): GNOME-Disks-ERROR **: Error getting udisks client: Error calling StartServiceByName for org.freedesktop.UDisks2: GDBus.Error:org.freedesktop.DBus.Error.TimedOut: Activation of org.freedesktop.UDisks2 timed out
[1] 4229 trace trap (core dumped) gnome-disks

Something is wrong on my Ubuntu 15.04 machine. Even when I slot in an USB stick it won't always recognize it. Sometimes it does after a reboot.

Any ideas what this could be?

In journalctl I see these interesting lines. Might be relevant:
