You may remember this post from last week…

Minni was able to fix the problem by installing the latest version of Alice 2.2…

The crash happens when it tries to playback a sound file. I tried using both WAV as well as MP3 files, but all give the same error. In fact, I have never before been able to playback any soundfiles within Alice.
