Cygwin + subprocess.Popen error

[Kis Gabot]

I got error at this python line:
(out, err) = subprocess.Popen( cmd, env=env, stdout=subprocess.PIPE, stderr=subprocess.PIPE ).communicate()

cd tmp
python gcovr.py .

Cygwin version: V1_7_9_advanced, included python: 2.6
Nothing other is locking the files.
