stdout argument of Application class cannot be set with relative path

What steps will reproduce the problem?
1. Application(..., stdout='logs/blabla.txt')

What is the expected output? What do you see instead?
Should create the file and write standard output into it. Instead no file is 
created.

What version of the product are you using? On what operating system?
2.3

Please provide any additional information below.
It works if only the filename (basename) is provided, e.g. stdout='blabla.txt'
