Dear openoffice.org maintainers, I've fixed the problem. I get an idea of the solution from the message I sent to the list at http://lists.debian.org/debian-openoffice/2003/debian-openoffice-200306/msg00072.html . Since the error message seems to indicate the problem was caused by X not able to find the bsmi* fonts (for Big5 truetype fonts), I decided to remove all the local configuration files and remove the ttf-arphic-bsmi00lp and tfm-arphic-bsmi00lp and did "defoma-app -v update x-ttcidfont-conf truetype" and then restart x. Then openoffice.org comes back to life.
However, I'm not sure why there was such a problem with the ttf-arphic-bsmi00lp package. Since I usually do not use Big5 fonts, the removal is fine for me. Unfortunately, it crashes much more frequent than before (when using OOo 1.0.2 and earlier). Thanks for your attention and I guess you may close the bug if you like. shouxun
