sorry for not getting back to you sooner, I somehow lost track of this.

This bug is still not fixed for me in version 2:1.1.3-3. In my case,
the problem is, that the source device doesn't start with /dev/mapper.

I have attached another patch, which is equivalent to my previous
patch, but this time using canonical_device().

Cheers,
