I've just run under gdb, with /etc/passwd giving a non-existent home
dir. The first warning about not being able to create ~/.gnome2 comes
from within gnome_vfs_init(). The `hash_table != NULL' assertion
failure comes from within gnome_vfs_transform_get("file"). Ah, I see
that gnome_vfs_init returns a boolean indicating success or not, which
Inkscape is ignoring. It would be nice if gnome_vfs_init documentation
were explicit in saying that one shouldn't call other gnome_vfs
functions if it returns false. (E.g. copy from gnome_vfs_initialized
documentation.)
I suggest that the fix is to search Inkscape source for use of
gnome-vfs, and make them all conditional on gnome_vfs_initialized()
(falling back to the corresponding !WITH_GNOME_VFS behaviour if not
initialized).
See also http://bugzilla.gnome.org/show_bug.cgi?id=340234, requesting
that gnome-vfs not require $HOME to be writable (or rather not requiring
~/.gnome2 to exist or something).
As for whether Inkscape should test $HOME before calling g_get_home_dir,
that's (in effect) being discussed at
http://bugzilla.gnome.org/show_bug.cgi?id=142568 (discussing the desired
behaviour/documentation for g_get_home_dir). It has been suggested in
that discussion that ignoring $HOME is a good thing; so I suggest
waiting a bit to see how that discussion develops before changing
inkscape to prefer $HOME over g_get_home_dir. (FWIW, my current opinion
is that we should prefer $HOME over getpwent, but I'll see what further
evidence gets posted to that discussion.)
pjrm.
