In my list of snapper snapshots there is one snapshot of type 'single' that, apparently, is empty (at least there are no files listed on 'show changes'.

However, when trying to delete this snapshot snapper crashes.

This is the effect when I try to delete it from a terminal

Code:
snapper delete 1154
Deleting snapshot failed.
How can I get rid of this thing? Any ideas?

Cheers
Harvey
