I found this information in bugzilla from a link posted earlier in this thread:
"We started the update process for gvfs on 11.1. I think the update is ready in September and you can get it through the normal update channel."

here to see the bug.
What I did was to add a traditional Gnome Main Menu (right click in the panel bar and choosing "add to the panel") and removing the slab main menu. When the update comes, I'll use the new menu again.
