Comment (by rlaager):

 Instead of using fopen(), fwrite(), & fclose() all over the place, would
 it make any sense to use purple_util_write_data_to_file() instead?

 Speaking of which, excluding API/ABI concerns and compatibility with old
 versions of glib, could we replace purple_util_write_data_to_file() with
 g_file_set_contents()?
