Mark, please would you enable the debug messages
as described in the docs,
viz. the following settings in lvm.conf:

  log {
          file="/tmp/lvm2.log"
	  level=7
	  activation=1
  }

then look at /tmp/lvm2.log after running the
problematic command?

The log file will show you the actual parameters 
that were passed to device-mapper leading to
the error messages.
 
Please put the log file(s) somewhere on the web and 
post URL(s) to the list - or mail the log file(s)
to me privately as a *compressed* attachment.
