Comment 3 for bug 1153777

confirmed on Windows 7, Inkscape 0.48.4.
the file Donate_CMYK.tiff leads to the exit message:

(inkscape.exe:3092): GLib-WARNING **: GError set over the top of a previous GError or uninitialized memory.
This indicates a bug in someone's code. You must ensure an error is NULL before it's set.
The overwriting error message was: Couldn't load bitmap

(inkscape.exe:3092): glibmm-CRITICAL **:
unhandled exception (type Glib::Error) in signal handler:
domain: gdk-pixbuf-error-quark
code : 5
what : Failed to load image 'C:\Windows\Temp\Donate_CMYK.tiff': InvalidParameter

...........................

on Windows XP, Inkscape rev 12174, both of these files fail to load, with the same message as above
