Description:
If you right click to open the context menu for table actions in the expanded Tables list in the schemata explorer after running a query against the schema (BEFORE it's been expanded in the schemata explorer), Workbench hangs and must be Force Quit.

How to repeat:
1. Run SELECT statement against a table in a schema that has not yet been expanded in the schemata explorer
2. Expand schema in schemata explorer
3. Expand Tables list under above schema in schemata explorer
4. Right click on a table in Tables list to open table actions context menu
5. Enjoy spinning beachball cursor as workbench hangs
6. Force quit workbench from dock (reopen to begin using again)

Fixed as of MySQL Workbench 6.0.4, and here's the changelog entry:

Opening the context menu for a table in the expanded tables list in the
schemata explorer after running a query against the schema (before it was
expanded in the schemata explorer) would cause MySQL Workbench to freeze.

Thank you for the bug report.
