jmacs crashes with SIGSEGV when opening multiple files

Binary package hint: joe

$ jmacs foo bar
Processing '/etc/joe/jmacsrc'...Processing '/etc/joe/ftyperc'...done
done
Segmentation fault (core dumped)

According to gdb, the error occurs in main.c:434 which reads
  p_goto_bol(bw->cursor);
One can easily see that bw in this case will always be NULL.
Upstream has commited a fix, but not released it yet:
http://joe-editor.cvs.sourceforge.net/viewvc/joe-editor/joe-current/main/main.c?r1=1.5&r2=1.6

Applying that patch to the joe sources fixed the issue for me, at least on Gentoo: http://bugs.gentoo.org/283508
It would be great if this straight-forward fix from upstream could be included with the joe package for Karmic.
