Incorrect use of g_assert. An assertion is a test for things that
shouldn't happen so in this case it's saying:

  * this function assumes files will always successfully open

Which is not the case. It's quite possible that a fopen will fail and
the correct behaviour is to handle the error, not assert out.



Good catch! That is a low grade fault, i will correct it! Thanks, Alex
