Public bug reported:
I have a DVD backup. If I open with a player or lsdvd I get the following
messages and the application terminates with a segmentation fault. I installed
the libdvdread4-dbg package and started the application with gdb to get the
last (hopefully helpful) message about ifoFree_PGC:
*** Zero check failed in src/ifo_read.c:894
for pgc->subp_control[i] = 0x6d6f7266
*** Zero check failed in src/ifo_read.c:894

Program received signal SIGSEGV, Segmentation fault.
