Researchers analyzing low-quality software rely on historical data, particularly on when defects were introduced into codebase. The SZZ algorithm and its variants track modified lines in bug-fixing commits to identify bug-introducing changes. However, SZZ struggles with accuracy, especially in cases of unrelated modifications (tangled commits) or missing references to external files (ghost commits) in the version control system. Our research explores whether incorporating bug discussions can improve SZZ by identifying relevant files. Using a dataset of 12,472 Mozilla bug reports (RoTEB dataset), we analyzed a sample of 369 reports and found that files are referenced in discussions for various reasons, such as system dumps, bug description, or solution draft, and they are valuable. Augmenting SZZ with this information improved precision in identifying bug-introducing commits but had little impact on recall. Our findings highlight the potential of bug discussions in enhancing SZZ, paving the way for further refinements. Data: https://zenodo.org/records/11484723
