MySQL Workbench on Ubuntu 12.04 doesn't starts after latest (Jun12) updates

This is the solution that resolved my problem:

I (kind of) fixed mine by going to /home/username/mysql/ and renaming (or deleting) the workbench folder.

It's ok and now my Worbench runs very well!

Canonical and God knows what went wrong. But here is a fix:

Download:

For 64 bit systems: http://launchpadlibrarian.net/56565535/libzip1_0.9-3ubuntu0.1_amd64.deb

For 32 bit systems: http://launchpadlibrarian.net/56565266/libzip1_0.9-3ubuntu0.1_i386.deb

Once downloaded, double click to install.

Now Download the latest version of My SQL workbench, Its for 11.10 but will work on 12.04. Make sure you download the version (32bit or 64 bit) suitable to you: http://www.mysql.com/downloads/workbench/#downloads

Once downloaded, double click on it to install.

And you are done.
