Thanks for reporting the bug!

Have a look at t/README to run the tests with command line arguments. (I usually run tests as ./tXXXfoo.sh -d -i -v -x with these arguments, though I cannot remember what each of that does. One of it makes the test suite stop on a failing test, such that you can cd into the testing directory and check the state of the file. (Which are present, which are gone?)

With these arguments it is also very verbose, and it would tell you what is wrong (is the assertion wrong in the `test_path_is_file/missing` or is it `git clean` segfaulting?)

As Johannes said, it makes sense that you debug into that as no one could reproduce it thus far on their system.

Thanks, Stefan
