Can´t play or queue folder with music

Hi,
single musicfiles can be played or queued without any problems, but a whole folder doesn´t work.
If I try to queue, the little "sun" is flickering for a short time and thats all.
I´m pretty sure it worked some day.

Ipod-Touch 4 with IOS 6.0.1
xbmcRemote 1.21
XBMC 11.0 on a Windows-PC

With the Android-App v0.8.8-beta1 Revision 808
on a HTC One V with Android 4.0.3 it works perfect.

I Hope you can help me -_-

PS: Antworten auch gerne in deutsch :-)
