Bug #60640	Workbench crashs very often

Description:
When using Workbench, the application crashes and terminates unexpectedly very often during a variety of different actions. For example:

- In modeling tool, if I double click an entity to edit its columns
- In SQL editor, if I right click an entity and choose "Alter table"

These actions are what I do more frequently.

How to repeat:
- In modeling tool, double click an entity to edit its columns
- In SQL editor, right click an entity and choose "Alter table"

I get a crash with 5.2.33 (connected to local 5.1.41 server) on 32-but Ubuntu 10.04 every time I try to ALTER table in SQL Editor. This is what I get when start workbench from the terminal:

openxs@ubuntu:~$ mysql-workbench 2>&1 >/tmp/trace.txt

For me it only seems to happen in KDE when the GTK+ Style is set to QtCurve. Changing the GTK+ Style to Human or running workbench in Gnome stopped the issue for me. 

Also it didn't happen with all tables but it always happened with the attached table

It seems that has something to do with scrolled window. See error message below:

Diogo, what gtk/gnome theme do you use?

Hi Alfredo,

Currently I'm using Macbuntu-10.10. I've tested running Workbench with Ambience Theme (Ubuntu's 10.10 default theme) and I realized you were right: the crash did not occur anymore (at least when selecting alter table option).

I would appreciate a lot if I could use Workbench with Macbuntu theme - prior versions worked fine.

Thanks
