I came across this log message today, too. Looks like
SetCurrentSubtitleTrack() calls AttachReceiver() on the
PrimaryDevice() which is cXineDevice in my case.

Looks like Transferring() isn't set at that time and therefore a
cLiveSubtitle instance is created although none is needed in
transfer mode (which is the only way how my setup works).
