Description:
For a while workbench crashes when I try to open a connection (which worked well so far). It says (I translated from hungarian):

My system:
Win 7 64 bit, 16G mem, MySQL Server 5.6

Some addtional info:
- Connection: Standard (TCP/IP), localhost:3306, root
- I tried to delete connection and recreate it
- When I recreating it the "Test connection" button works (can connect)
- The bug maybe related to video card (I changed my video card)
- I tried with my old and new video cards (with the newest drivers)
- I tried to uninstall / reinstall both 5.2 and 6.0.7 workbench
- I tried to delete C:\Users\<myusername>\AppData\Roaming\MySQL\Workbench

How to repeat:
Change video card (?)

Thank you for the bug report. Are you able to provide the output of Help->System Info ?. Thanks.

Of course (in 6.0.7):

Can you rename your WB configuration directory and try again? You can find that dir with the Help -> Locate Log Files command and then going a few folders up. 

If that makes the crash go away, please zip the old config dir and upload so we can analyze what could be causing it.

Dear Alfredo, the crash remained same.
The dir you mentioned was: C:\Users\Laci\AppData\Roaming\MySQL\Workbench
I renamed it, but again:

(The configuration dir was recreated.)

Please try version 6.0.8. Thanks.

6.0.8 works well, thank you!

Thank you for the feedback.
