Created attachment 5441 picture of a network link with %20 in it I noticed if i connected to a network link location that has a space it in, thunar has it as '%20'. I think the slashes before and after the name should also be removed, similar to how dialogs in abiword and firefox show it.
Fixed in http://git.xfce.org/xfce/thunar/commit/?id=65adfa6552f2211e51caa0c23ecbbefc5ab96362
