Bug#648562: gtk3 applications abort on errors XI_BadDevice

[Goetz Gaycken]

Package: libgtk-3-0
Version:  3.2.1-1

After updating to gtk3/gnome3 applications I experience frequent
application aborts due to "XI_BadDevice (invalid Device parameter)" see
below. The equivalent gtk2 applications handled the XI_BadDevice
without aborting. I experienced the problem also in earlier versions of
libgtk-3-0 e.g. 3.0.12-2

The XI_BadDevice seems to be caused in my case by a (not so uncommon)
hardware problem which leads to disconnects and reconnects of the USB
keyboard and touchpad of my Macbook pro. When using gtk2 applications
the problem only lead to a short interruption during which the touchpad
and keyboard was not functional.  After the touchpad and keyboard
get reconnected everything works normally, except for the gtk3 applications
which abort (see below for error messaes) [The disconnects and
reconnects also occur under OSX and are from a user point of view
hardly noticable].

After updating to gnome3, the "disconnects" also abort the
gnome-session i.e. I get logged out whenever this problem occurs.


With many regards,
  Götz Gaycken

This probably reflects a bug in the program.
The error was 'XI_BadDevice (invalid Device parameter)'.

  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
