[Bug 1391857] Re: libcairo segfaults when rendering video streams, e.g. youtube videos in webkit based browsers

[Sebastien Bacher]

SRUed to trusty as well

** Description changed:

- The libcairo version (1.13) that is used on Ubuntu 14.04 contains a bug
- the leads to a segementation fault (see
- https://bugs.freedesktop.org/show_bug.cgi?id=81699) when rendering
- certain video streams.  E.g. webkit based browser that render Youtube
- videos will eventually crash.

+ try to open https://www.youtube.com/watch?v=b1XGPvbWn0A in midori browser

+ * Regression potential
+ check that GTK and webkit still work correctly (no segfault, no rendering issues)
+ 
+ -----------------------
  
  The bug has been fixed upstream, libcairo 1.14 does not segfault, so it
  would be very desirable that the libcairo2 package in Ubuntu gets
  updated to version 1.14 of libcairo.
