When I tried to put the big bib file on a page (it's too big), I got
an "internal error" rather than an error from you that would have
allowed me to smoothly fix the problem using your interface.

I read this to mean there isn't adequate error reporting when a file is too big to add to a page when using Special:ImportProjectFiles (rather than the importprojectfiles script, for instance). Please correct if I misunderstand.
