Handbrake: 0.9.9-7

After recent upgrades to dependent libraries, Handbrake crashes with a segfault trying to open any MKV source file. The specific library seems to be libdvdread, which was upgraded September 20 (4.9.9-1 -> 5.0.0-1), although related libraries were upgraded at the same time including libdvdcss, libdvdnav, and libbluray. Running Handbrake under strace produces the following output right before the crash:

Thanks for the report. The issue was that Handbrake was using a bundled older version of libdvdread which was incompatible with the system libdvdcss.

handbrake 0.9.9-8 shouldn't have this problem as it uses the system provided libdvdread.
