BUG/MEDIUM: lua: converters doesn't work

Browse Source 
The number of arguments pushed in the stack are false, so we try to execute a
function out of the stack. This function is always a nil pointer, so the
following message is displayed.

   Lua converter 'testconv': runtime error: attempt to call a nil value.

Thanks Michael Ezzell for the repporting.

This patch must be backported in the 1.6 version.
