Some more info on this. It turns out that the problem stems from having
text in the footer. Multiple fields, or single fields are not a problem,
but any text causes that segfault. This happens on both headers and
footers, and is irrespective of other document content. In fact, images
in headers/footers works, as long as there is no text.
The next step is figuring out when this broke. It appears to have broken
more than one week ago, but I'll let people know what I find out.
This also gives me an idea for a regression test suite. `yes | abiword`
must not crash opening any of the documents in test/wp/. I'll set up
the nightly build script to do this eventually.
