/etc/mime.types comes from Apache, not from Gnome... the latter one uses
/etc/mime-magic.dat, which seems to be derived from file's database
/usr/share/magic.

Sorry, this was an "improvement" I indroduced some time ago... the idea was to
get a better guess for the mime type, which does *not* depend upon looking at
a file's extension, but at it's contents (like `file' does). But...

Unfortunately, this has not been fixed in gnome 1.4/Ximian, at least with the
RPM's for LinuxPPC. Although it is not really likely that you ever attach
something which is a "370 XA sysV pure executable", this file is ~40% broken.

Wow, that's good!!!

As an alternative (or additionally) you could do the following:

* edit the file /etc/mime-magic, find the offending line, and change the last
field to a valid entry (like "application/pdf")

* run gnome-gen-mimedb, which re-creates /etc/mime-magic.dat

Not really good, but it solved the PDF problem for me.

Hth, Albrecht.
