I was installing the latest when I loaded it on my box... but mere hours later (like 5 or 6), a new snapshot was released and I updated to it.
I'll update my system for the day now, reboot as usual after the update, and see if the Patches error occurs again. If it does, I'll post the info here... and if I can get Snort to error again, I'll see if I can find that report and add to it if necessary.
Edit to add: Looks like System Patches is working properly now too... so who knows what I was running into at first.
