New subject: Hollywood+ card working??

Hi everyone,
i have experienced some strange behaviour of my plain vanilla vdr.
When vdr reaches the end of a replay it segfaults. Core file analysis
showed the following backtrace:
#0  cUnbufferedFile::Seek(long, int) (this=0x0, Offset=0, Whence=0) at
tools.c:884
#1  0x080dab2c in cFileName::SetOffset(int, int) (this=0xb56a1540,
Number=3, Offset=0) at recording.c:1345

#3  0x0809d8e1 in cDvbPlayer::NextFile(unsigned char, int)

#6  0xb7fbab63 in start_thread () from /lib/tls/libpthread.so.0
It seems that vdr tries to access a reference to an cUbufferedFile
object in cFileName::SetOffset which is a null pointer. The following
quick and dirty hack solved the crash, but as I don't know this code
deep enough it may have other side effects.
