12.2 RC 2: Bug With Kaffeine

Has an issue playing mp4 videos. They play for so a certain amount of time, then the screen goes black and the progress bar just jumps ahead in increments to the end. Seems to do this on every video I’ve tried.

FYI - I do not have a bugzilla account and the bug reporting faq directed me here. Let me know if there is additional info I can provide.
