fix-small-bug

Implement one small fix in the repository if possible. Your change must fix a concrete clear bug if you found one. (Otherwise do nothing.) Constraint for the change/fix:

• It must be very clear that the issue you fixed is really a bug.
• The fix must not break anything. (Adapting testcases if the test-case is also flawed is allowed.)
• The fix is not allowed to cause much effort or refactoring.
