Ok .. i had another closer look and noticed line 231 wasn't the only
occurance of the 64-bit pointer truncation.

I filed a bugzilla report on it (and added a patch to the
bugzilla-report).

http://bugzilla.gnome.org/show_bug.cgi?id=331971

This patch fixes the eog crashes on my system and should probably be
reviewed/committed to MC-gnome.
