I'm having some trouble getting a good trace of the problem.
I tried a variety of ways to get an strace. First, I just tried to
"strace oowriter file", but this would terminate before I did anything
to the file--something about the way oowriter releases control from the
terminal I think.
So then I started it up, inserted a footnote, got the hang, and did an
strace -p on it and got this output, going out forever.

Then I tried to start up the program, and strace -p it before inserting
the footnote, and see what happens when I insert footnote. Then, I was
no longer able to get it to hang.
I suspect that this bug might have come from a corrupted document.
Between getting the first two straces, and trying to get the third when
I could no longer reproduce it, I used a full "Save As" to save a backup
of the file. After I did this, I could no longer reproduce the problem
on either document.
Thanks for the quick reply,
Daniel
