bui-agent v0.61 does not exit on error when it should

Hi,

I have updated my burp setup to current 2.2.12. Since the burp switch '-v' is become '-V', I patched my current burp-ui 0.61, based on one of your patches included in 0.70. So long, it works but I noticed a glitch.

Running bui-agent with

/usr/bin/python3.4 /usr/bin/bui-agent -c /etc/burp/buiagent1.cfg

I get the following output which is pretty obvious:

The "[Burp2]" section is DEPRECATED and will be removed in v0.7.0. Please use the "[Burp]" section instead.
Unable to determine your burp version: Command '['/usr/sbin/FMIBackupOne', '-v']' returned non-zero exit status 1

The problem is that the agent won't exit on this error, and so my service files can't detect that the agent is faulty. If not resolved in v0.70, would it be possible to make bui-agent exit on that failure ?

Best regards, Ozy.
