Terminating app due to uncaught exception

We have 10.6.3 version of macmini machine , when we run packagemaker command to generate .pkg we got Segmentation fault message.

We have given the command below to generate .pkg .

/Developer/Applications/Utilities/PackageMaker.app/Contents/MacOS/PackageMaker -d ./source.pmdoc -o ./output/macout.pkg -v

Segmentation fault

when we run packagemaker command alone we got the below exception message. Actually it was working fine before changing of our machine ip address, after changing we are getting the below error message .

PackageMaker[44583:903] -[NSKeyedUnarchiver @8@0:4]: unrecognized selector sent to instance 0x21ab30
