bogofilter/bogoutil concurrency crash?

I just build the latest stable release of bogofilter (0.11.1.3) on Mac
OS X with Berkeley DB 4.1.25.
Then I trained it with a bunch of messages (1135 spam, 16546 good).
While I was training it, I ran into a crash. I was running a script
which was doing
bogofilter -n -I mbox
and while that was running in one terminal, I was using bogoutil in
another, and bogofilter in the 1st died.
Exception: EXC_BAD_ACCESS (0x0001)
Codes: KERN_INVALID_ADDRESS (0x0001) at 0xdbdbdbd8
Thread 0 Crashed:
#0 0xdbdbdbd8 in 0xdbdbdbd8

#4 0x00002788 in _start (crt.c:267)
#5 0x00002608 in start
I can reproduce this at will by doing the following:
In one terminal execute
bogoutil -d goodlist.db | more
leave that running, and in another do
bogofilter dies in the way described.
Is anyone aware of the bug? (I'm not familiar with the source or
Berkeley db, but I can try to debug the problem given pointers.)
I was about to put bogofilter into production use in my .procmailrc
Should I be concerned about this problem and hold off? (I didn't seem
to be able to recreate the crash with 2 bogofilters, but definitely
with a bogofilter and a bogoutil running.)
