Status changed to 'Confirmed' because the bug affects multiple users.

I just got this while 'scrubbing' (quickly scanning through the timeline by repeatedly pressing the right arrow button while playing) through an imported FLAC file.

When recovering the open projects, some files had become corrupt.

I should add that I'm using Audacity 2.0.0 64 bit on Ubuntu 12.04.
