Hi guys, Just one click away from the linked bug 820303, namely in https://bugzilla.gnome.org/show_bug.cgi?id=765382 it was clearly concluded -- and confirmed even by a Remmina developer -- that it was a bug in Remmina, accidentally triggered by a (not buggy) change in VTE.
Again, repeating: It is clearly known to be a Remmina bug (with patch available) and by no means a VTE bug. Please act accordingly. e.
