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
P6
0 0
255
$ 

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 ?
MemoryError
