This is a known bug that appears both in Annotator. When you change from one 
song to another, depending on how the number of segments varies, it crashes. 
Also in some circumstances, clicking on a song that still has no descriptors 
extracted also crashes. We hope to fix both bugs on the next release to come 
this month.

Meanwhile you can avoid the bug by running the extractor by yourself. You can 
see the the command to execute, by clicking on one of the included songs and 
lauching the extractor (engine icon), just change the parameter that is the 
wave file. After that, just add the file and click it. It should work.

Also, if you want just to see the chords but you are not interested in other 
extractors, you could try the new app 'chordata' which is available as 

It shares the bug but the problem will only appear eventually when changing to 
a second song, but the first time you open and choose a song will work
