When g_option_context_parse fails, context and error variables are not getting free'd
which results in memory leaks. Free'ing the same.
And replacing g_error_free with g_clear_error, which checks if the error being passed
is not NULL and sets the variable to NULL on free'ing.

When file name consists of characters from other languages, say korean,
then it throws an error
Error initializing: Invalid byte sequence in conversion input
Hence setting locale to all to fix this.
And changing the media-info argument to type G_OPTION_ARG_FILENAME
