Tvheadend

Hi,

my setup is the following:
Raspberry Pi 2 -> Xbian
I have a DVB-C USB tuner connected and running.
tvheadend is up and running for all free tv channels.
For encrypted channels I use OSCam (cccam).
Tvheadend and OSCam are connected via dvbapi.
As soon as I switch to an encrypted channel, tvheadend crashes immediately.
The consol just shows a "Bus Error" and the exists tvheadend.

This is my oscam.conf

[global]
logfile = stdout
fallbacktimeout = 3
bindwait = 5
nice = -1
maxlogsize = 200

Any idea what to do?
