ok, what ive found:

os.chdir('very_long_path')
# works

os.listdir('very_long_path')
# gives:
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: listdir() argument 1 must be (buffer overflow), not str

os.chdir('very_long_path')
os.listdir('.')
#works

os.chdir('very_long_path')
os.path.getmtime(os.listdir('.')[0])
#throws exception (path not exists)

os.chdir('very_long_path')
open(os.listdir('.')[0])
#throws exception (path not exists)
