The information in bug reports influences the speed at which bugs are fixed. However, bug reports differ in their quality of information. In order to determine the elements that developer widely use to fix bugs and the problems frequently encountered, we conducted a survey among APACHE, ECLIPSE, and MOZILLA developers. The analysis of the 156 responses shows that steps to reproduce and stack traces are most sought after, while inaccurate steps to reproduce and incomplete information pose the largest hurdles. This insight is helpful to design new bug tracking tools that guide reporters at providing more helpful information. Our CUEZILLA prototype is a such tool and provides reporters with feedback on the quality of new bug reports and recommends to add missing elements. We trained CUEZILLA on a sample of 289 bug reports, rated by developers as part of the survey. In our evaluation, CUEZILLA was able to predict the quality of 31-48% of bugs reports accurately.
