timeshift loops forever when mounting mdadm root device

[andrearuggirello]

upon launching TimeShift, the program seems to hang forever, with CPU usage at around 14% on my kubuntu 14.04/amd64 box.

Attempting to launch it from the command line, several times, I always receive an endless list of repeating errors:

$ sudo timeshift

(above rows repeat... forever :)

...

Note that /dev/md127p1 is an mdadm array (RAID0)

It seems timeshift is attempting to mount the device but couldn't succeed.
This system was cloned via rsync from a "regular" one (without md devices), where I'm successfully using TimeShift - the only difference being in the mdadm root device.
