Failing test TestFileSourceCodeProvider.test_get_lines on openSUSE

Packaging pudb for openSUSE and when running tests I get this:

The same for pudb-2018.1.

Here's the FileSourceCodeProvider constructor. It doesn't appear to accept a random string ('test file name'), but rather a filename. And it seems unlikely that mocker.Mock() returns something that should be assigned to debugger. But calling canonic on it doesn't throw an error, so maybe it's OK:

class FileSourceCodeProvider(SourceCodeProvider):
    def __init__(self, debugger, file_name):
        self.file_name = debugger.canonic(file_name)

Works fine for me on 2.7:

I wonder what the difference is between your and my environment.
