(Assuming you've checked that device-mapper snapshot support 
is compiled/loaded into the kernel)

Please turn on full debugging and look for the last few sets 
of lines starting with 'Adding target' and 'dm'.  [Lines
starting with other things are probably irrelevant here.]

Also check for kernel log messages from device-mapper 
(e.g. /var/log/whatever).

See example.conf for details of how to log to a file, or run
with -vvv flags.  If you prefer you could send us (dm@uk.sistina.com)
the whole (compressed) log file for the command and we'll take a 
look.
