Description:
Got "MySQL Workbench has encountered a problem. Attempted to read or write protected memory. This is often an indication that other memory is corrupt."

Note it would ne nice if clicking on the report bug option filled in the error message details for me. Or, if that's too hard, at least make the message copyable to the clipboard.

How to repeat:
Click to create a new server connection. Choose "Take parameters from an existing connection". Choose an existing connection (which happens to be an ssh tunnel). Click Next.

When you'll get the same error message again, please, right click somewhere in the error dialog box with no text and use Copy stack trace to clipboard context menu item. Send stack trace to this bug report.

I encountered this "Attemp to read or write to protected memory" so followed the instruction to copy the stack trace by right clicking on the error dialog box. Another MySQL Workbench Unexpected Error surface upon right clicked on the dialog box. The message was

************** 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.
