spoke too soon: though LD_LIBRARY_PATH=/usr/lib/firefox worked for the test case above, it doesn't seem to work in general. if i modify the test case to use render_data instead of load_url, for example, i get the core dump.
interestingly, my crash seems to be here: #0 0xb714f037 in gtk_moz_embed_get_title () from /usr/lib/firefox/libgtkembedmoz.so Dump of assembler code from 0xb714f037 to 0xb714f057: 0xb714f037 <gtk_moz_embed_get_title+4071>: mov (%eax),%edx 0xb714f039 <gtk_moz_embed_get_title+4073>: movl $0x0,0x4(%esp) 0xb714f041 <gtk_moz_embed_get_title+4081>: mov %eax,(%esp) 0xb714f044 <gtk_moz_embed_get_title+4084>: call *0xec(%edx) 0xb714f04a <gtk_moz_embed_get_title+4090>: mov %eax,(%esp) 0xb714f04d <gtk_moz_embed_get_title+4093>: call 0xb714b860 <[EMAIL PROTECTED]> 0xb714f052 <gtk_moz_embed_get_title+4098>: lea 0xffffffdc(%ebp),%edx 0xb714f055 <gtk_moz_embed_get_title+4101>: movl $0x0,0xffffffdc(%ebp) End of assembler dump. noticing the call to gdk_window_get_parent, if i modify my code to ensure that my MozEmbed is parented before i invoke any methods on it, my program becomes crash-proof. (touch wood!) this seems not to correspond to where others above claim to have been crashing, but it certainly seems to be where i always crash on edgy/firefox 2.0.0.1.
