After updating Mysql Workbench from version 5.x.x to 6.2.4 with Mysql Installer there is a critical Problem with saving diagrams.

I opened my old model/diagram, which I had  created before with Workbench 5.x. After saving this diagram Workbench crashes and the original model/ diagram was deleted by Workbench. This is very big shit! This was about 7 days ago.

In the meantime I tested a litte bit.
- I removed Workbench 6.2.4 (x86) with Mysql Installer from PC.
- Then reboot.
- Renaming old installation directory with "_"
- Adding Workbench 6.2.4 (x64) with Mysql Installer on PC.
- Same bug as before.

So I tried to create a new diagram. After adding a single table and then to save this simple diagram there is also a complete crash of the program.

I don't find any solution to save a model without crashing.

Attached you will find a screenshot after the crash and also a logfile with Debug-Level 3.

Please help me fixing this problem.

Kind regards,

How to repeat:
- Start Workbench
- Add a new model
- Add a new diagram
- Add a new table
- Add some columns
- Save the diagram

Suggested fix:

I think that the old Workbench version was 6.1.4 (x86) from which I made a update to 6.2.4.

Thank you for the bug report. Please check if the folder name is affected like bug http://bugs.mysql.com/bug.php?id=74231 ? Thanks.

Folder name was before and after update:
D:\xxx Thomas Drießen\Projekte\xxx\Datenbank

After changing the folder name to following - saving works fine:
D:\xxx Thomas Driessen\Projekte\xxx\Datenbank

It would be fine, if a bugfix is available for this. ;-)

Kind regards,

I had the same problem wşth workbench
I found out that if the target directory or sub directories names has Turkish letters like "ıüğişçöÜĞİŞÇÖ" , workbech crashes.
When I change them to similar English letters like "iugiscoUGISCO" it saves normal.
I use Windows 8.1 English with Turksh locale settings.
Kind Regards,

I had the same problem with workbench build 592. The workbench crashes when using portuguese letters like 'ãõé'.
The problem was solved when I removed this letters.
I use Windows 8.1 Portuguese with English local settings.
