Check to see if the file exists before loading it up in the web browser?
It will not help for other errors, but that might be the most common
one, eh?  If it's a local file, something along the lines of:

try:
    import urllib
    # This will raise an IOError if the file cannot be found
    fname_check = urllib.URLopener().open(fname)
    webbrowser.open(fname)
except IOError, data:
    print "ERROR: " + fname + "not found: " + data

might do the trick?  Of course, if fname is a remote file, I think
that's going to retrieve it if it does exist, which is probably not a
good idea if it is a large file...
