   Hi. I hate to say I'm happy this has happened to you, and I'm sorry
if it's cost you any time or frustration, but you are the first that I
know of to report exactly the same results I get. This segfault
happens because you are using a newer version of wine. I have found in
my own builds, both under FC2/Planet and Gentoo, that any version of
wine newer than wine-20040505 causes this problem. Switch to that
version and I suspect that you will get much better results.

   I spent the weekend, off and on, trying to debug this problem. I
think the problem is in the jack_fst program, but I cannot run that
program under gdb since it complains that it doesn't know how to
handle .dll files. Bummer. I need a program to point me in the right
direction. If one is reading and cares to help please contact me off
list as I'd like to ask a couple of gdb questions.

   BTW - I don't know that it matters, but it appears that jack_fst
utilizes some wine headers files, so for safety I would recommend that
after downgrading Wine that it's probably safest to rebuild fst and
jack_fst. I don't know that it matters, and actually I haven't seen
any problems not rebuilding, but I think when debugging things it's
probably best to remove potential failures that stuff like this could

Hope this helps,
