Re: Possible Evince -> Mozplugger Bug?

[Marco Pesenti Gritti <mpgritti gmail com>]

Mime detection needs improvement, there is already a bug open about
it. Right now we are just looking at the extension.

A possible approach would be to do extension matching first (it's
faster) and to fall back to content sniffing (slower) if the first
mime type was not in the list of supported mime types.

Anyone have thoughts about this?
