PGP 6 is really, really old.  It predates some of the OpenPGP  
standard, so I suspect a passphrase encoding problem between the two  
programs.  I suggest removing the passphrase completely (just hit  
enter when asked for the new passprase), then copying the key over to  
PGP, and changing the passphrase to what you want it to be.

That said, a signal 11 is a segfault.  If PGP is actually *crashing*,  
there isn't much you can do.
