I can confirm this bug. It happened to me while watching a 720p.mkv movie file and switching between vlc and chromium-browser. vlc eats up the whole free memory, Ubuntu starts to swap, Hard Disk is busy, took me about 5 minutes to open a console and kill vlc. Then I was able to use my laptop as usual.
