Description:
This can happen when you meet the conditions, to be displayed as a tool tip comment for a table on the diagram.
I only made sure in Japanese.
Maybe, I reproduce it in more than 20 chars.

How to repeat:
1. Open Workbench.
2. Create new model.
3. Add new diagram.
4. Add new table.
5. Enter "ああああああああああああああああああああ" in table comments.
   "あ" is a Japanese chars.
6. To put the mouse cursor to the table in diagram.
   # Then, the tool tip should appear normally.
7. Workbench will Crash after a few seconds :(

Thank you for the bug report. I couldn't repeat on the below system:

MySQL Workbench CE for Mac OS X version 5.2.47  revision 10398

Please provide a screenshot when the mouse pointer was positioned. Thanks.

I've attached a screen shot.
Since the crash Placing the mouse pointer, screen shots could not shoot last.

Is it situation to be limited if you are using a Japanese version of OS?
Incidentally, it was the same situation in `Mountain Lion`.

Thank you

Bug #68630 is a duplicate

Fixed as of the upcoming MySQL Workbench 6.0.3 release, and here's the changelog entry:

Adding a particularly long string (around 50 characters) to a table
comment for a model diagram would cause MySQL Workbench to crash.

Thank you for the bug report.

Windows 7
Workbench 6.0.6
------------------
when I hover or drag the mouse on a model (table comment and some fields comment is Thai language) ex. "ข้อมูลพนักงานภายในองค์กร" , "รหัสพนักงาน"

There are 2 cases of error:
1 - Workbench shown "External components has thrown an exception"
2 - If not thrown exception - Workbench show messed up tools tip (not readable)

I'm affected by this bug with MySQL Workbench 6.0.8 in Linux (64-bit). The error I get from the console is:
