[evolution-patches] 45063, more etree api workarounds

[Not Zed <notzed ximian com>]

this can't be done in the message-list since it doesn't know which
message the folder-browser has displayed.

this probaly introduces other races (e.g. select one, goto another, go
back very fast, perhaps), but what can you do eh
