from the djvu viewer package ?

try running ldd /usr/bin/djview and look for some "missing" lines
(perhaps a broken dependency)

i really can't tell without a proper back-trace

Yes, the Djvu package.

please try 3.5.12 from ~arch and tell me if the crash is still there

ACCEPT_KEYWORDS="~x86" emerge djvu

then retest

That worked. Thanks.

I've just marked 3.5.12 stable on x86. I don't have time to fix
djvu-3.5.9 atm and if the problem doesn't occur with the recent
version of djvu, I hope this is the best thing what I can do.
