Bug#798763: vlc: segfault if vlc and libvlc5/libvlccore8/vlc-data out of sync

[Lionel Elie Mamane]

Package: vlc
Version: 2.2.1-3
Severity: serious
Justification: Policy 3.5

after upgrade, vlc started segfaulting on startup. This was solved by:

[UPGRADE] libvlc5:amd64 2.2.0~rc2-2+deb8u1 -> 2.2.1-3
[UPGRADE] libvlccore8:amd64 2.2.0~rc2-2+deb8u1 -> 2.2.1-3
[UPGRADE] vlc-data:amd64 2.2.0~rc2-2+deb8u1 -> 2.2.1-3
[UPGRADE] vlc-plugin-pulse:amd64 2.2.0~rc2-2+deb8u1 -> 2.2.1-3

which suggests that dependency on at least one of these packages is
too lax (should be more strictly versioned).

here's the backtrace for reference (without symbols)
