Splunk webservice won't start due to Python error?

[markdflip]

I recently installed Splunk on my Windows machine and the process completed. However, when I try to go to the splunk web interface, I am unable to connect. Searching the webservice log provides the following issues. It seems to by Python related, but I am not sure what these errors mean.

The issue ended up being in the mimestype.py.

I added the following code in line 254 of the file.

try:
                    if '\0' in subkeyname: # new
                        print "Skipping bad key: %s" % subkeyname # new
                        continue # new

File was checked with
python -m tabnanny mimestype.py
