Eli> Why do you think the comma is the culprit? 

Cause, if I simply edit the message and replace the comma with a dash
in the mime attributes, it works like a charm.... 

[thinking....] 
Which of course makes me realize the problem is not in the name..... I had
an excel session open on that file (but it was hidden in one of my
virtual screens.....), so changing the name removed the lock conflict.

So this is not really a bug. However, the error message "invalid
argument" is misleading. Since what really happens is that a lock is
taken by excel and not a problem with the given file argument. Isn't
there a more precise error report available, like "file being locked
by other application"? 

Thanks anyway.
