Hi. The patch I sent yesterday was not good enough, because I found afterwards the way upstream fixed this issue:
https://github.com/pymzml/pymzML/commit/428329dd10fac5ae5fd2e72ffa6c0153d6e39491 This confirms that the file does not really belong to the package, it's a short-lived file created only when running the tests. So, I decided to apply the upstream fix, because it allows debian/rules to be simplified a little bit. The upstream patch can be dropped when we package version 2.6.0 (which I leave to you). Thanks.
