[Nut-upsuser] upsd crashing when stopped

[Kris Jordan]

Windows 7 Pro x64 SP1
NUT 2.6.5-4

upsd is crashing when stopped and I think it has only started with the 
latest version. Nothing shows up in 5'D upsd output, the normal output 
just quits. Windows 7 event log output below.

It's also crashing on XP, though I do have one XP system where it 
doesn't crash. One difference on WinXP is the upsd process gets stuck 
running and doesn't close, like it does on Win7, so I have to end the 
task manually before I can start NUT back up.

It happens on my clean test machine with a different driver too, so it 
will probably be easily reproducible.

Regards.
