This is a strange backtrace: how come XUNTAG called recursive_edit_1? I'm guessing this is because your binary is optimized, and so the backtrace is not really reliable. Can you rebuild Emacs without optimizations, preferably configured with --enable-checking=yes, and run Emacs under GDB, so that we could both catch the error before the crash and get a better backtrace? Also, please report all this via "M-x report-emacs-bug RET", so that it's recorded in the bug tracker. Anyway, this cannot be due to your configuration, because the reason for the crash is most probably an invalid NULL face, which should never happen. Thanks.
