compiz crashed with SIGSEGV in _M_data() from operator==() from ExtensionPluginAnimAddon::prePaintOutput()

[Vitaly Korolev]

Compiz crashes after latest updates. Panel loads along with launcher, but then after a few seconds they both disappear and crash reporter shows up. Firefoxmanaged to appear without a window frame to let me report this here. Can't access anything else..

This crash seems to be related to once of the additional compiz addons. Once I disabled Animations addon and Bicubic filter the crashing stopped.

Status changed to 'Confirmed' because the bug affects multiple users.

I can confirm that after disabling Compiz Animations Plugin, system returns to stable.

[Moebius (roblukas)]

Narrowed down to Animations Add-On.
Normal Animations continue to function.

I was having this. Removing compiz-plugins-extra solved it
