Nautilus crashes when associating applications to unknown file types

Thanks a lot for the patch.

It improved the situation in such a way that now
`gnome-file-type-properties' crashes.

The backtrace looks very much the same as before the patch (with debug
info, not stripped, but not very informative).

Speaking of backtraces: Is it possible to disable bugbuddy and to force
gnome applications to generate core dumps?

When I launch g-f-t-p manually, there is no crash, but my choice for a
handler program is ignored.

In this context it might be interesting to know, that files, that are
reported as "ASCII English text" by the `file' command, are listed as
"Unknown type" in Nautilus.

File types, that are properly classified by nautilus (e.g. PostScript
documents), are nicely opened.

One issue here is (or maybe it's by design), that the embedded ggv view
control ("View as GGV PostScript Document Control") is only used in the
old-style tree view of nautilus.

For the new spatial view, the external handler application is used,
regardless of the choice in the control center.
