@flybyray Can you add a test that would reproduce the problem?

I tried to reproduce, but could not. See #1075

[flybyray]

@asolntsev your test runs within the play testenviroment. the dependencies manager is invoked differently. your test should be in the style of python tests from 'samples-and-tests/i-am-a-developer'.
i try to add a test there.

[flybyray]

@asolntsev i added a test flybyray@1307f79

and the problem is related to system environment "LANG". If it is not set it will crash. i checked it with the print out of "declare -x". if not set it will result in:
