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. Mark
