Hi, I installed sfepy 2015.2 on ubuntu 14.04 lts, and ran the tests. The only one that failed was the one mentioned on the subject. This is what I got after running the debug.

<<< directory: tests, test files: 1
<<< tests/test_input_navier_stokes2d_iga.py
sfepy: left over: ['verbose', '__builtins__', '_filename', '__file__', '__package__', 'TestInput', 'input_name', '__name__', 'output_name', '__doc__']
sfepy: left over: ['data_dir', 'verbose', '_filename', '__builtins__', '__package__', '__name__', '__doc__', '__file__']
>>> test instance prepared (1 test(s))

Any help or clarification would be greatly appreciated.
