Possible bug with snd_seq_event_input_pending

Hi, I don't know if this is a bug or not, but I'll report it in case it is.

If I configure my client as follows:

snd_seq_set_client_midi_version(seq, SND_SEQ_CLIENT_LEGACY_MIDI);

snd_seq_set_client_ump_conversion(seq, 0);//I disable ump conversion

And then I send a midi event from a MIDI 2.0 device, the snd_seq_event_input_pending(seq, 1) function will not respond until it receives any other legacy event.

Now I know that with SND_SEQ_CLIENT_LEGACY_MIDI I shouldn't disable ump conversion, but I expected it to return 0.

Thank you
