[webkit-gtk] Compatibility issue with WebKitGTK+ 2.12.1

[Michael Catanzaro]

Hi,

A security vulnerability fixed in WebKitGTK+ 2.12.1 has introduced a
compatibility issue with applications that use HTML5 localStorage on
local URIs. In particular, it broke lightdm-webkit2-greeter. We are not
currently aware of any other affected software; if you know of any free
software commonly included in Linux distributions that would likely be
affected by this change, please let us know immediately.

Although distributions must upgrade immediately as always, consider
leaving 2.12.1 in your updates-testing repository or equivalent for
longer than usual.

For further information and a workaround:

Thanks,

Michael
