Evolution image/pjpeg inline display (again)

[Gavin Hamill <gdh@acentral.co.uk>]

Hi :)

I'm a longstanding Debian user (running sid at the moment) so have Evo
1.4.5, and am experiencing the problem listed in the subject, that
image/pjpeg attachments are not displayed inline, but am only given the
option to Save Attachment.

I've found quite a few references to this on the web, but have yet to
come across a solution.  It's especially maddenning because the
thumbnail in the Evo message pane is correct, but yet I must save the
attachment and view it externally.

I've had a poke in /etc/mime.types and mime-magic, etc. but without
joy... one message suggested to use gconf to force Evo to deal with
image/pjpeg inline.

This sounds like a plan, but I've been a KDE user up until now, and am
running KDE3 at the moment, with the various GNOME libs installed solely
to support Evo... how would I go about convincing Evo to display these
images inline?

Thanks,
Gavin.
