Description of problem:
Evolution seems to think the text "gnome-fs-ftp.png" should be a link.
Specifically, the "ftp.png" part - "ftp://ftp.png". It seems pretty
obvious that this should not be a link to me. 

Here are some possible criteria to consider for the following
question: Should this string be a link, even though it lacks a
protocol prefix (like 'http://') and any slashes?
- NO if there are less than 2 dots in it (skip things like www.foo,
ftp.foo)
- NO if there is random junk before it (like 'gnome-fs-')
- NO if the characters between the last dot and the end of the string
are on a blacklist of common file extensions (but what about .COM files ;)
- YES if the characters between the last dot and the end of the string
are on a whitelist of valid TLDs

Obviously, the last criterion would be both slow and a pain to
maintain, and the third one would be highly subjective. Personally, I
like the first two... any ideas?
