[vdr] Crash in cPatFilter::Process at si.h

Hi!

VDR 1.3.24 segfaulted with the following backtrace: #0 0x080bae41 in cPatFilter::Process (this=0x824a948, Pid=0, Tid=0 '\0', Data=0xb57f2414 "", Length=40) at si.h:301 #1 0x080c82cc in cSectionHandler::Action (this=0x824a570) at sections.c:214 #2 0x080d9920 in cThread::StartThread (Thread=0x824a570) at thread.c:227 #3 0xb7f573b0 in start_thread () from /lib/tls/libpthread.so.0 #4 0xb7de026e in clone () from /lib/tls/libc.so.6

The line libsi/si.h:301 is "obj=ret;". The getNext function is called from pat.c:288. I don't understand these C++ template thingies, so maybe someone could look at this.

It may be worth to notice that I'm using NPTL.
