I think I have tracked this one down...
After running strace against "firefox --debugger", I see the following:
stat64("/usr/share//mime/mime.cache", {st_mode=S_IFREG|0644,
st_size=47708, ...}) = 0
open("/usr/share//mime/mime.cache", O_RDONLY|O_LARGEFILE) = 54
fstat64(54, {st_mode=S_IFREG|0644, st_size=47708, ...}) = 0
mmap2(NULL, 47708, PROT_READ, MAP_SHARED, 54, 0x100000) = 0xb4415000
--- SIGBUS (Bus error) @ 0 (0) ---
+++ killed by SIGBUS +++
After mv'ing /usr/share/mime/mime.cache out of the way, I can Ctrl+O in
firefox without a SIGBUS.
So either mime.cache is simply corrupt or firefox can't handle some of
the data in there. This doesn't happen if I download the firefox binary
from the Firefox website. So it appears to be specific to the Debian build.
Can maybe other people try to mv /usr/share/mime/mime.cache out of the
way and see if it fixes the problem? Does anyone know how to "rebuild"
this file in case it is corruption (although I doubt it is)?
HTH.
David.
