g_get_home_dir() can return NULL on Unix, too, if for some reason
there is no passwd entry for the user. Not that common, true, but can
easily happen for instance if you name service (like NIS+, NIS or
LDAP) is temporarily down. But anyway, one should always check for
NULL return value from it. I now notice that gtkfilesystemwin32.c
doesn't check ... Will have to fix.

Presumably not, as the environment variable HOME is used only if no
passwd entry is found. You would have to make getpwuid(getuid()) fail,
too.
