Error after installnig Splunk Enterprise Security 5.0 Install on 6.3 leads to web integer literal error

[doodoodonk]

I installed 6.3 Splunk Enterprise and then went to install Splunk Enterprise Security 5.0 SPL and after the installation completed. The web interface never came back up. Nothing was listening on port 8000. I checked the web log and it failed to startup due to a literal error in the root.py file. Not really sure why this is happening. Any clues to a solution to fix this?

When I look at root.py. This is where the error happens.

if global_cfg.has_key('log.error_maxsize'):
    splunk_log_handler.maxBytes = int(global_cfg['log.error_maxsize'])
