Can't display html attachments

[Robert Broughton <rbrought smartt com>]

I've just started using balsa v0.9.3, and have a recent version of helix. (The
Gnome control center is v1.2.1.) When I get an email with an html attachment, and
attempt to open the attachment, balsa tells me "No view action defined in gnome
MIME for this content type. Content TypeL text/html." I've gone into "Mime
Types" in the control center, and both "open" and "view" are defined for text/html.
Help!
