Omniback configuration problem

Oracle 9.2.0 on Solaris 2.8 on a Netra X1. Omniback 4.1

I'm trying to configure my new installation for Omniback, and getting core dumps:

# /usr/omni/bin/util_oracle8.exe -CONFIG orainst2 $ORACLE_HOME sys/oracle <blah, blah>
+ configOra8App orainst2 /opt/oracle/product/9.2.0 sys/oracle
./util_oracle8.exe[17]: 14537 Segmentation Fault(coredump)
./util_oracle8.exe[34]: 14539 Segmentation Fault(coredump)
./util_oracle8.exe[34]: 14541 Segmentation Fault(coredump)

./util_oracle8.exe[21]: 14558 Segmentation Fault(coredump)
./util_oracle8.exe[17]: 14560 Segmentation Fault(coredump)

Doesn't matter whether I try from the Omniback GUI, which shell etc etc Any ideas gratefully received.

thanks
