Crash on FreeSWITCH 'bad' EVENT (double Content-Length)

[nttranbao]

Hi,

For some reason, FreeSWITCH returns an event with double "Content-Length" as below, which causes esl.py to crash.

While I can report this to FreeSWITCH team, is there anything that we can do on greenswitch to get around this issue? (i.e. removing duplicate lines)?

Thanks,
Bao
