Details:

On debian squeeze i686, gnash 0.8.9 from tarball, with:

./configure --prefix=/usr/xxx --disable-menus --enable-renderer=agg
--enable-gui=fb --disable-plugins --disable-sound --enable-media=none
--enable-input=touchscreen

I got segmentation fault by launching fb-gnash. Here is the backtrace:

Program received signal SIGSEGV, Segmentation fault.
