I propose this patch is applied. It is best to require the very latest of
gmime 2.6 version at this time (gmime 2.6 maturing...)

This will make id:"1331402091-15663-1-git-send-email-tom.prince@ualberta.net"
stale. It can be reworked by changing $IFS to something else in code.

(We might start requiring some gmime 2.4 versions to be present; For me
 some tests fail when using gmime 2.4.21 (with gmimg 2.4.25 all works ok) --
 and then Reworked Tom Prince's patch could be used to overrile this
 "restriction")
