OK, looking at the screenshot you sent Jonathan (it's sort of cool/amusing - maybe
you should send it to the list ;-), I think the problem is that FriBidi is
assigning essentially random bidirectional levels to the text, which then
causes the bidirectional-reordering code to go to work.

As for why this is happening on your system, I don't know -- it might have 
something to do with endianess, but I think other people have gotten GTK+-1.3.2
to work on Solaris.

Anyways, the code to debug is
 
 pango/pango/fribidi.c/pango_log2vis_get_embedding_levels()

It's sort of complex code, but the result should just be one directional
segment at level zero, so seeing where that goes wrong may not be hard.
