Looking at the server code, I see that a 400 response happens when the server 
side pcap2har conversion script returns an error code.  This could be due to an 
invalid pcap file, a problem with your python setup, etc.

I added some code to make it clear what is going wrong.  Please sync your copy 
of webpagetest to r1198 or higher.  In the file 
www/webpagetest/mobile/pcap2har.php, find the following lines:

// Debugging flags.  Set to false by default.
define('FORCE_LOGGING_OF_PCAP2HAR_ERRORS', false);
define('RETAIN_PCAP_FILE_ON_ERROR', false);

Set both defines to true.  Now on errors, logs describing the problem will be 
written to www/webpagetest/mobile/log.txt .  Add that log to the bug, and I 
will have a better idea of what is going wrong.
