Among the problems experienced by developers, incomplete information was, by far, most commonly encountered. Other common problems include errors in steps to reproduce the bug, errors in test cases, bug duplicates, incorrect version numbers, and incorrect observed and expected behavior.

Finally, errors in stack traces are highly unlikely because they are copy-pasted into bug reports, but when they do happen they can be a severe problem.
Other major problems included errors in test cases and observed behavior. A very interesting observation is that developers do not suffer too much from bug duplicates, although earlier research considered ...
