The classification of bugs in functional languages is an understudied area, as opposed to imperative counterparts, such as Java. This paper acts as an initial step to cover this gap into two complementary directions. First, a dataset of 142 bugs from 10 Haskell FOSS repositories have been classified according to two taxonomies from literature in order to assess how well they handle the differences in programming paradigms. Based on our bug classifications, the first taxonomy has very little variance in types of bugs, with 86% of bugs being classified in the same category. On the other hand, the second taxonomy showed more potential as the bugs were more balanced between categories, but with occasional difficulties in classification, as some bugs fitted more than one type. Second, we performed interviews with four Haskell developers about their experience with bugs and the usefulness of these taxonomies in practice. They argued that while such taxonomies can prove useful, the context in which it is being used is more important. Thus, circumstances such as the size of the project and team, and stages of development need to be taken in consideration before trying to apply any taxonomy.
