Bug fixing is one major activity in software maintenance to solve unexpected errors or crashes of software systems. However, a bug fix can also be incomplete and even introduce new bugs. In such cases, extra effort is needed to rework the bug fix. The reworking requires to inspect the problem again, and perform the code change and verification when necessary. Discussions throughout the bug fixing process are important to clarify the reported problem and reach a solution. In this paper, we explore how discussions during the initial bug fix period (i.e., before the bug reworking occurs) associate with future bug reworking. We focus on two types of "reworked bug fixes": 1) the initial bug fix made in a re-opened bug report; and 2) the initially submitted patch if multiple patches are submitted for a single bug report. We perform a case study using five open source projects (i.e., Linux, Firefox …
