Well, like I mentioned, the r.in.tiff in GRASS beta8 has a nasty bug.
It would segfault with truecolor tiffs (which would leave a core file if
your machine is so configured).  I still can't see how it would matter
whether you are using X or not (unless that matters to libtiff).  Sure
it's not an overconsumption of memory?

Anyway, if you want to get the CVS versions of r.in/out.tiff and if you
still have problems, then I'll do more investigation.  Maybe we'll be
making another release before too long.
