Oh, wait, there's a newer version… this was with 2.0.0, which was somehow installed to /Applications/Audio. Have also found version 2.2.1 in Xcode 4.1 folder (/Developer/Applications/Audio), as well as 2.2.1 in Xcode 4.2 folder. 2.2.1 does not crash. So… never mind? This issue has been verified as resolved and can be closed.
