MySQL Workbench on Ubuntu 12.04 doesn't start

Question

MySQL Workbench was working fine till today. I installed the regular updates and now it just doesn't start. When started it 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:

/home/atul/.mysql/workbench/wb_state.xml:1: parser error : Document is empty

^ /home/atul/.mysql/workbench/wb_state.xml:1: parser error : Start tag expected, '<' not found

^ /home/atul/.mysql/workbench/user_starters.xml:1: parser error : Document is empty

Answer 1

delete the file wb_options.xml and then give a try.
