GTK program badness 10000 in recent rawhide

[Pekka Pietikainen]

GTK programs started acting really badly after a recent rawhide update +
system restart. As in I couldn't login anymore. That combined with the evdev
breakage (ctrl-alt-f1 and backspace did nothing) made for a really fun (not)
recovery, only way of getting to a text console was either rapidly pressing
ctrl-alt-f1 after logging into gdm or booting into runlevel 3.

When starting the programs up 

The program 'gnome-session' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 21 error_code 3 request_code 2 minor_code 0)
  (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.)

ends up in .xsession-errors (or stderr if you run them manually). Most 
of the time. Occasionally the program starts up just fine.

xterm/twm and KDE are fine. In fact, if you start up KDE the GTK apps
start up just fine there (xterm+twm don't have that effect). Running the programs under 
gdb or ltrace also seemed to make them nearly always.

Will poke a bit more later...
