Hi Paul,

thanks for helping with improving NX code. I am one of the Debian  
maintainers of nx-libs-lite as well of the release manager of X2Go, a  
terminal server solution that uses nxproxy and acts as upstream for  
the packages in Debian.

I test your patch and it results in several nxproxy crashes every 1-2  
minutes. The output of the session.log file you can find below.

Please check nxproxy when working together with nxagent (deb  
http://packages.x2go.org/debian jessie main) and hopefully you can  
find some changes for your patch (as I would love to have BIG-REQUESTS  
support in NX).

PS: I also noticed that nxproxy still has the old maintainer  
registered in Debian BTS. Please make sure that you Cc: our team  
mailing list (pkg-x2go-devel at lists.alioth.debian.org).

PPS: @Matthew Johnson: I have asked the debbugs maintainers, if they  
can change something on the override files, so that the mails for  
nxproxy end up on pkg-x2go-devel (and not in your INBOX).

Greets,
Mike
