missing recordings

I am quite sure I found a problem. I believe it isn't mentioned yet.

My environment:
xbmc 12.0 (on OSX 10.7.5)
PVR and VU+ / Enigma2 Client addon Version 1.6.6
a dreambox dm7025 as backend with some autotimer and multiple recording directories

I am impressed from xbmc and the pvr support. Many thanks.

the issue:
The display of the recordings in xbmc doesn't display all recordings from all directories on the dreambox.

I enabled the debugging and noticed that the directory iteration in the recording scanning process stops if an empty directory is found. All remaining directories don't get scanned.
Removing or filling the empty directory on the dreambox confirms the assumption.
-> The directory iteration continues to the end or next empty directory.

e.g.
if files on dreambox
/hdd/movie/ (contains 2 recordings)
/hdd/movie/eureka/ (contains 1 recordings)
/hdd/movie/lost/ (contains 1 recordings)
then all 4 recordings are displayed in xbmc
-> ok


if files on dreambox
/hdd/movie/ (contains 2 recordings)
/hdd/movie/eureka/ (empty)
/hdd/movie/lost/ (contains 1 recordings)
then only 2 recordings (/hdd/movie/) are displayed, missing one from /hdd/movie/lost/
-> nok
