This bug manifests itself in a number of different ways. All seem to be
related to no data being populated in what should be the ListModel
panes. Another way to observe this issue is to run mysql-workbench and
open the sakila_full model. Once open double click on one of the tables
in the diagram. At the bottom in the middle is a pane that should have a
"column" tab. Click on that tab and should see that it is blank.
Normally that pane would have a list of all the fields and their
attributes and allow you to add/modify/delete any of the columns.

This bug is a regression caused by changes in GLIB >= 2.42.2. It is
rather severe in that it affects many aspects of the workbench from
querying databases to editing the EER disagrams.

This bug has been identified previously in Debian here:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=763356

The issue is a glib regression with glib >= 2.42.0 . Oracle provided a
patch (referenced in this bug report) here:

http://bugs.mysql.com/file.php?id=21874&bug_id=74147

The upstream bug associated with that patch can be found here:

This bug has been fixed in Vivd Vervet (15.04) as can be found here:

I am attaching a debdiff patch that seems to work well to resolve this
issue on Ubuntu Utopic Unicorn (14.10) and is the same patch
(libglib2.42.patch) applied to mysql-workbench (6.2.3+dfsg-6) in Vivid
Vervet (15.04)
