Subject: Bug in PC/import_nt.c
From: Dan Pierson <dan@remote.control.com>

RegistryQueryValue requires that its fourth argument be initialized to
the length of the buffer being passed in, this wasn't being done. I
also split the call and status test into two lines with a local variable
so that I could look at the status in the debugger.
