Application that crashed: rosegardensequencer
Version of the application: 1.7.3
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.29.6-217.2.8.fc11.i686.PAE i686
Distribution: "Fedora release 11 (Leonidas)"

What I was doing when the application crashed:
Attempted to start Rosegarden from the desktop menu. Got an immediate crash report from the Rosegarden sequencer program. This is 100% repeatable, and has continued to happen over many yum upgrades of Fedora Core 11. Sound card is M-Audio Audiophile 2496 (doesn't matter whether on-motherboard soundchip turned off or not). Also fails when M-Audio Fast Track Pro USB sound/MIDI module is plugged in.
