I've seen this error twice today, while trying to create a step file to
install a Windows 2008 R2 64-bit guest (the Win2008-64 step file
available on the git repository doesn't work for me). This happened when
the guest was being rebooted by the windows installer. The contents of
the screen dump file are this:

$ cat /home/ehabkost/autotest/kvm-autotest/client/results/default/kvm_runtest_2.Win2008.64.install/debug/scrdump.ppm
0 0

And the 0x0 pixmap really makes gdk panic:

>>> (w, h, data) =  ppm_utils.image_read_from_ppm_file('/home/ehabkost/autotest/kvm-autotest/client/results/default/kvm_runtest_2.Win2008.64.install/debug/scrdump.ppm')
>>> w,h,data
(0, 0, '')
>>> gtk.gdk.pixbuf_new_from_data(data, gtk.gdk.COLORSPACE_RGB, False, 8,  w, h, w*3)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?

> The guest is still running, but stepmaker isn't recording any more so it's
> boned at that point.  And of course, it's near the end of a guest install so
> one has lost a decent amount of time...
