Xbian reboots while playing mp3

[handjebij]

After a long struggle with a i2c display i finally had everything running smooth ,
but now i suffer with a new problem when i start playing mp3 sometimes i can play 1 or 2 files and even in some occasions a full album but then Xbian reboots

I have no problems with playing 1080p movies with DTS so it seems not to be a power problem
(ac is 1 amp)

because i had done a lot with the image i decided to install a clean image of xbian RC2 without any extensions but also then MP3 fails constantly

is this a known bug (i searched the forum but can't find any other with the same problem)

i am running the mp3 from a SMB share on my NAS (the same i use for my movies)

any help is welcome
