To answer my own question, this was the issue - apparently the call to spice_main_channel_clipboard_selection_release() actually clears the clipboard. Removing this call allows the clipboard from client (Guacamole) to Spice server to function properly. I'm not sure if there's anything that needs to be done to "ungrab" the clipboard after sending the data, or if it is done automatically?
