Looks to me like it changed between lxsession and lxpanel by having a
second copy of the path prended to it, but without the trailing /

If it wasn't for the '/' difference I'd guess that whatever sets up
XDG_DATA_DIRS is following common pattern of prepending to a path like

XDG_DATA_DIRS=/some/directory1:/some/directory2:$XDG_DATA_DIRS

And that script is being called twice so you get two copies. Could
still be something like that, but the path getting processed in some
way before concatenating
