A 'const gchar **' is (in this case) an array of 'const gchar *' (ie:
const string pointers). It is the strings that are immutable. The
array itself is fully writable, and indeed you should free what
g_variant_get_bytestring_array() returns to you, using g_free().
By the same token it is therefore perfectly acceptable to pass it
through a gpointer.
Cheers
