Error loading theme icon

[Zhong Ren]

I am new to wxPython, but I managed to write some test
programs successfully.  There is one error that I cannot
resolve so far.  Could someone help?  All the png's below are
indeed there.  I am puzzled by "invalid window size".  Is this
an installation problem?  Thanks.
