As Patrick and Gary said, looks like a trouble with a /tmp directory
(protection?) or its file system (full or out of inodes).

Older versions of MIME-tools (5.419 and older) use IO::File->new_tmpfile
to create a temporary file (typically in a /tmp directory), and return
a silly diagnostics "Invalid argument" on encountering any problem.

Versions of MIME-tools starting with 5.500 use File::Temp->new instead.
On a failure this returns a much more sensible diagnostics.
