Script import_logs.py seems to hang at log format detection if first line of the log is a wierd request.

I run import_logs.py in daily crontab -> I first grep the access logs for yesterdays date and then import that using import_logs.py. Unfortunately, it seems that first request yesterday was a bit wierd. That seems to break the script's log detection and script hangs indefinitely.

This is the log file which causes it to hang:
