Mr. Project files on my system are currently identified (by the evils of
content sniffing) as xml files. Consequently, they are not openable from
nautilus. Grrr...

This brings up a potentially bigger usability problem - the current file
type system within Gnome is very confusing. And this isn't just the
perspective from a dumb linux newbie, this comes from a long-term linux
user who just got back to using Gnome for the first time in a couple of years,

I mean, I run into the above mentioned problem. I create a Mr. Project file
and then try to open it back up. Instead, I get an XML viewer. So I try the
standard "Open With..." option that I expect to work.

Instead, I get options for configuring the xml mime type.

So I check out the advanced desktop preferences where I remember seeing
something about file types. Come to find out, the file type for Mr. Project
files is configured just fine. This leads me to the unfortunate feeling
that Gnome is broken - the kind of feeling that would lead less loyal users
to a feeling that Gnome sucks.

So I dig around for a while. I think, "Hey, I bet the Gnome Help can help."
Well, nope - not at all. All I get is documents taking showing me
everything I already saw, all of which seemed to look right, but still was
not working right.

So I google a bit and discover the EVILS of content sniffing - evil to me
simply because EVERYTHING I AS A USER COULD SEE within Gnome was file
extension oriented and working correctly.

Instead, the file sniffing part was completely undocumented (as far as I
could find, and I did look - perhaps I just missed it). And the only way to
fix it seems to be to login as root (not something that all users could do)
and go fix /etc/gnome-vfs-mime-magic, which is a royal pain.

Basically, when it all comes together, my conclusion is that indeed the
system IS INDEED broke. And NOT just in some "fix the mrproject mime type"
sort of way. Rather, the way that it all is presented to the user is
confusing and bad.

There's my two cents. Thanks for all of the hard work on Gnome. Overall,
the perspective of this "just got back to Gnome" linux user is WOW - this
is AWESOME! :)

Just wanted to report the problems/usability issues as I ran into them.

Thanks,
