************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

fix confirmed.
will be included in 5.2.11

An entry has been added to the 5.2.11 changelog:

If the Home screen was closed and then an attempt made to reopen it from the View, Home main menu option, then MySQL Workbench crashed.
