Description:
Change to Workbench window, where I had an old session. Scaled up to full-screen and klicked on scale down (-) button.

Got a crash with the following message - some module crashed, but as the message does not mention what module, error code, log file with details etc I feel rather limited here?

After acknowleding that pop-up, it behaves normal - until next time I click on scale up/down (+/-) buttons, or the 100% dropdown, then the same pop-up returns again.

After restarting Workbench fully it works again to scale the model.
  
Pop-up message:

" MySQL Workbench has encountered a problem

  Ett undantagsfel har inträffat i en extern komponent.

  We are sorry for the inconvenience but an unexpected exception has been raised by one of the MySQL Workbench modules. In order to fix this issue we would kindly ask you to file a bug report. You can do that by pressing the [Report Bug] button below.

How to repeat:
Failed to myself.

Had a suspicion it was related to having a mysql Connection window open at the same time, as there are old long-time bugs still present in my installation despite the comment it should be fixed - see Bug #89257 for that.

However, I could not repeat this easily again. Opening model, opening Connection, running a few queries, going back to the model and scaling - works this time.

Suggested fix:
For the error message popup, add a line "For technical details, see the log file at /path/to/log" 

This would keep the Clean "userfriendly" message, while providing actual information to those that want it. And make it easy to attach the log here.
