--- Comment #5 from Ken Thomases ken@codeweavers.com 2013-04-17 16:58:47 CDT --- I was able to reproduce the crash of foobar2000 on Alt-H with the X11 driver. I had to configure XQuartz's preferences to make the Option key send Alt because Command-H does hide XQuartz. But once I did that, Option-H crashed the same way.
So, it's not related to the Mac driver.
It seems to be in the drawing of menus.
