It's all described in the man page ... it may take a few reads to figure it out (it took me a few *years* to figure it out, actually ...) But I don't really think the problem you are running into has much to do with XGetWindowProperty, but rather what the function is doing with the data it gets back. The code to split the WM_CLASS return is buggy. You can find the details of how WM_CLASS is defined in the ICCCM (probably on your system in some place like /usr/share/doc/XFree86-doc-4.3.0/ICCCM/) However, the function needs to be robust against the data not matching what is defined to be in the ICCCM.
