[vdr] femon 0.1.4 crash on crypted channels

[Nicolas Huillard <nhuillard@ghs.fr>]

I experienced a plugin crash when femon is on screen and I change 
channel to one that is declared as encrypted in channel.conf.
If a channel is encrypted but not declared as such in channels.conf (for 
whatever reason, maybe because this channel never had enough strengh and 
thus VDR didn't receive any data ever), the plugin doesn't crash.

Here is the gdb backtrace :

Program received signal SIGSEGV, Segmentation fault.

It also crash with the classic skin :
