fix
when using glretrace to dump the GL state, sometimes
_mesa_get_color_read_format and _mesa_get_color_read_type can access
uninitialized ctx->ReadBuffer->_ColorReadBuffer
To reproduce run:
glretrace -D 137078 wine-preloader.137078.trace
trace file is here:

I've attached a sample patch to fix the bug (probably incorrect) and a gdb
backtrace .
