assertion in _gcry_ath_mutex_lock

I'm getting assertions w/ openldap 2.1.20 compiled against
gnutls-1.0.16 & libgcrypt-1.2.0.  

I've tried several versions of gnutls & libgcrypt but the failure mode
is constant across all the versions I've tried.  I've attached a stack
trace.  The other active threads differ from crash to crash, but the
asserting thread is constant.

If there's other debugging info that would help, just let me know.  

Thanks
job


here's what I'm currently running (debian testing base):

gnutls-1.0.16.tar.bz2
libgcrypt11_1.2.0.orig.tar.gz
libtasn1-0.2.10.tar.gz
opencdk8_0.5.5.orig.tar.gz
openldap2_2.1.30.orig.tar.gz
