VLC fails when subtitles are completly out of sync

[Martin Constantino–Bodin]

How to reproduce: choose -70,000s for the value of the subtitles’s delay (they were really out of sync) and restart the video from the beginning.
Instead of playing normally, VLC seems to freeze.
In my case, this then lead to a crash during apport-bug was looking for issues.

I don’t know whether it is related, but when using the “g” and “h” keys to set the subtitles delay, the delay stops being displayed when the delay become large (more than a minute in my case).

Best regards.

This is an unsupported release now. Please think to install the next LTS 'Bionic 18.04'
