In here, (pkgsource.sites[n]->key ) is apparently evaluating as a zero
length string. This should never happen (key must have a value).

However, I'm pretty sure the sites class allows key to have no value, so
what you need to do is to go to frame 2 or 3 and identify the package
and site count that it's got. And then work backwards to find out when
the invalid site is created. 

Can you do that? I'll offer what email assistance I can, but until we
have enough detail to reproduce here, that's all I can offer. I'm
obviously keen to get this bug fixed...
