[Libvncserver-common] ctypes server crashes after client connect

[Hart's A. <bha...@ya...>]

I'm having some problems getting a basic server running, hoping someone with more vnc experience than me can give me some clues what i might be doing wrong.thanks

script crashes after client connects, client shows blank screen for one second before server segfaults.server iterates 5 times before crash.  tested on ubuntu10.10
is this incorrect?	array = ctypes.create_string_buffer( '\1\2\3\4'*WIDTH*HEIGHT )	serverPtr.contents.frameBuffer = ctypes.cast( array, ctypes.c_char_p )
