I'm fighting with this too. Symbol fonts have major problems being printed
on Gtk. I suspect that something even more serious is happening with them
too.

Twice I've saved a test document with symbol fonts and both have turned up
as "bogus documents".

I suspect we problems in our import/exporters.

Here is my little script to run gdb. One of the world's great programs in
IMHO.

This will give you the command line
gdb>

from which you can set breakpoints and define variable to be traced like:
ie

break fv_View.cpp:4890

then run AbiWord with

gdb> run

You can control-C at any time, inspect variable etc and continue with

gdb> continue

Anyway, explore it, it's an extremely useful program.

Cheers
