	Nice :-) well that means we get wonderful debugging symbols with string
dumping & all.

	These are beautiful :-)

	It'd be really nice to try to step through the constructor with 'n' 'n'
'n' to see where it bombs out, if you can, or ...

	Oh - *((int *) NULL) = 42; is always quite a good one ;-)

	So - if we can't catch it inside gdb; I suggest a binary chop: add:
	try {
..
	} catch (const com::sun::star::uno::Exception &)
	{ fprintf( stderr, "Failed!\n" ); }

	around increasingly small section of code - until the unit test
passes ;-) The help is clearly not the problem, since the constructor
continues and we'd need to abort it before initializing the pObjShells -
but the next one is perhaps more so. Hopefully we can make some headway
with that.

	Thanks !

		Michael.
