Agreed. Moreover, this is basically undefined behavior, possibly
with security implications (who knows...).

The same issue, bug 832077, was reassigned to libgtk-3-0, but it
will just be "fixed" by silencing the warning. As

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=832077#112

says:

  That warning has been widely reported for countless packages and
  should be resolved by the app developer. Still, to keep people
  happy until then, it will be silenced by default in GTK+ 3.22.1
  (accidentally got omitted in 3.22.0)

So, the real bug is in the applications.

Bug#837072: GtkScrollbar and EmacsFixed are "drawn without a current allocation"

2016-09-18 Thread Leon Meier 

Also occurs for me for emacs24 version 24.5+1-7.
Emacs clutters the xterm from where it is launched completely, which 
renders xterm half-useless:


...

(emacs:12626): Gtk-WARNING **: GtkScrollbar 0x312c900 is drawn without a 
current allocation. This should not happen.


(emacs:12626): Gtk-WARNING **: EmacsFixed 0xd51130 is drawn without a 
current allocation. This should not happen.


...

I'm voting for raising the severity, since the bug affects several 
people and the usability of another application (xterm).
