Not sure if this is a valid bug to post here or not; yet since I was able to reproduce it 2 times plus and output suggest to post here.. see attached for terminal output and machine info. Please let me know if more info is required.
You use the classic r300 driver, which is now unmaintained. Is this issue present with the r300 gallium3d driver?
Works for me with latest Mesa git. Closing.
