Now I've undo the changes of the c-diff in vdr 1.1.28 and vd compiles
without an error. But when I start vdr, I get the same segmentation
fault. When I run "gdb --core=core" I get the following message:

Program terminated with signal 11, Segmentation fault.
#0 0x0807d161 in ?? ()

A "Backtrace" shows several adresses #0-#5.
Because I'm not familiar with gdb: what are the next steps to find out,
in which code-fragment the problem occur?
FYI: When I start vdr several times, I'll get the same list of adresses.
