(custom_command == NULL || sizeof(custom_command) <= 0)
custom_command is a gchar pointer, so, using sizeof simply gives you the
size of the pointer, not the length of the string.
"sizeof(custom_command) <= 0" will always be the size of a gchar pointer
(4 bytes on my system).
If you're looking for the length of characters in the string, try using
g_utf8_strlen() instead.
