MySQL workbench was working fine till today. I installed the regular updates and now its just doesnt starts. When started its just shows the 'opening screen' and nothing happens.

I tried re-installing it from synaptic but no luck. I use it all the time and now suffering a lot. Any help will be appreciated.

When run from terminal with: mysql-workbench --log-level=debug3 --verbose

It gives a long log. Please see at: http://pastebin.com/Z2t8pdZF

I see these error in the log but don't know what they mean and how it stopped working automatically,
