transaction doesn't rollback automatically

[GoogleCodeExporter]

I downloaded the source code and try to execute test module, but I always get 
below exception and the rollback doesn't work for me, please explain why this 
happens to me.

{"init terminating in 
do_boot",{{badmatch,{aborted,{{error,foo},{rollback_result,{updated,{mysql_resul
t,[],[],0,[]}}}}}},[{mysql_test,test,0,[{file,"mysql_test.erl"},{line,58}]},{ini
t,start_it,1,[]},{init,start_em,1,[]}]}}

thanks!
