[Baypiggies] Crossplatform exceptions.WindowsError help

This code must run cross-platform:

except WindowsError:

However, the WindowsError exception is only defined on Windows, not on 
Linux or Mac. How do I keep a spurious NameError from happening on the 
other platforms while still keeping the code clean (free from 
os-specific code blocks)?

I'm getting a WindowsError from some users sometimes, when doing 
webbrowser.open()[1][2]. I'd like to show a nice message rather then 
letting my global error handler kick in, but I have users on all platforms.


[1] It could be this bug, which I can't seem to open to investigate further:
(I get a message "Artifact: This Artifact Has Been Made Private. Only 
Group Members Can View Private ArtifactTypes.")

[2] Here's the traceback if you are curious:
