Aha! I don't have Debian (I run Gentoo), but I did manage to extract it
like that, and now there is some useful information:

If that backtrace is to be trusted, Exim's function dbfn_open() has
called the function __db_pg_free_read_4002() from the libdb library, and
somewhere in there is where things get stuck. Of course, Exim doesn't
call such a function by a name like that. It will be using the "open"
function pointer in the data structure it gets from db_create().
There have been several releases of libdb-4.2 (I'm running 4.2.52). I
wonder what you are running?
Anyway, this looks like something really horrid going on inside libdb. I
am not at all sure what we do now. Andreas?
