Well, the pstops filter used is the "alternate pstops filter". When implementing this stuff
(in order to better support the banner pages), I never thought of encountering names longer than
127 characters (which is the limit in at least PS level 2).

As there is still another bug pending with this filter (parentheses in the title string), I'll
fix this by putting it into a stopped context (without any notice to the user whatsoever).
I guess the fix will take place during the next week.

Drop me an e-mail if you have any complaints.
