browsing smb dir with spaces is impossible

[dragoran <dragoran feuerpokemon de>]

hello
I am using nautilus to browse smb shares.
it works fine the only issues is that it can not open folders with 
spaces in them.
It displays them as %20 and refuses to open them. After failing to open 
a folder it dissappers from the list.
If I mount the share I can browse all folders.
I am using FC4 x86_64 (gnome 2.10) : gnome-vfs2-2.10.0-5
Should I bugzilla this? Or is anything missconfigured?
P.S:
please CC me.
