Yesterday, I found out using live CD's that the problem only seems to
exists when using amd64 architecture.

Some thorough investigation by me and a friend (with better C knowledge)
has led us to the macro _G_TYPE_CIT, defined at row 1479 in
gobject/gtype.h of the glib headers. The segfault seems to be caused by
the pointer to __inst->g_class (__inst is defined using a cast of the
GpmEngine instance to a GTypeInstance inside the macro). valgrind gives
the error "invalid read of size 8" and whines about that pointer (found
by entering some fprintf's in the macro). Also, that pointer (as used in
the macro) is suddenly 64 bits instead of 32 bits like the rest of the
pointers in that macro. My friend is still digging deep in glib's
headers to get enlightenment on the issue.

The weird thing is that Hardy's version of gnome-power-manager, with
seemingly identical code for the problematic(?) files, still works just
fine... The Makefile's don't seem to have any strange differences
either.
