Description:
See Bug #80017

In short, attempts to import the attached .mwb file results in the message:

"Cannot open document [document name]

 Error unserializing GRT data
 string too long"

How to repeat:
File --> Open Model --> Select the .mwb file attached.

Hi Miguel.
Apparently I can remedy the situation by shutting down mysql workbench and opening it up again.
This problem seems to occur when you first create the .mwb file by saving a model, closing the model view, and then trying to reopen the model view by navigating to the saved .mwb.
This would make it impossible for you to recreate unless you had the entire database.
It's not solved, but let's consider this closed as it's not a blocker, has a workaround, and is probably an out-layer anyway.
