Bug #70309 Crash on start

Description:
For the past couple of days MySQL Workbench has been working perfectly. I start it today, after no irregular use or updates to my machine (as far as I can tell), and it simply crashes upon start. I don't have a chance to do anything but report a bug. I ran it through the command line, and received this exception:

Unhandled Exception: System.Runtime.Remoting.RemotingException: Failed to read f
rom an IPC Port: The pipe has been ended.

How to repeat:
It's news to me, I have no idea what to do or how to configure it. Now it just happens on start - immediately throws an exception/crashes.

Suggested fix:
None

Please check the workaround mentioned in bug http://bugs.mysql.com/bug.php?id=70262 (folder rename). Thanks.

The suggested fix worked. I renamed the folder, and when I started Workbench, it worked. It seems it auto-generated a new folder with the same name. I am guessing that I just had some bad data in there. I had to re-setup my connection again, but that was no big deal. Thanks for the quick help!

Thank you for the feedback.
