Which link exactly (between which two elements) produces this? It
usually means the two pads don't share a common format (caps).

You could do this before you try linking:

gst_debug_set_threshold_from_string ("*:6", TRUE);
 ... link ...
gst_debug_set_threshold_from_string ("*:0", TRUE);

to get some debug output about what happens during the linking process.
