--- Comment #3 from eliturner@me.com 2013-04-17 16:14:56 CDT --- Sorry about the typo, it it indeed "wine-devel @1.5.28_0". I am running Mac OS X 10.8.3 and have confirmed this behavior on two Macs configured with the same software.
I noticed you can hide the application by selecting "hide" within the dock menu for the application and it behaves as expected, however when you press command+h (which you mentioned maps to alt+h) it will intermittently crash the application. If the application does not crash, it executes the alt+h keystrokes as expected.
I've attached a backtrace and the application I am using is foobar2000 1.2.5 beta 2.
Thanks!
