Description:
I only want to do backup/restore operation at present so I have decided. not to configure the connection to the server via SSH.

When using Data Dump tab and Export to Disk. I choose more than one schema to export and immediately and dialog box occurs with the message: unhandled exception: local variable 'tables' referenced before assignment.

It works fine selecting a single schema.

How to repeat:
Go to Data Dump tab and Export to Disk then select the following options:
- Export to Self-Contained file
- Create Dump in a Single Transaction
- Dump Views
- Dump stored routines

Thank you for the bug report. Verified just as described. As soon as 2 schemata with one or more tables are dumped, I've got this exception. Workaround is to dump one by one...

An entry has been added to the 5.2.20 changelog:

In the Export to Disk tab of the Administrator's Data Dump facility, selecting multiple schemata for export to a self-contained file resulted in the following exception:

unhandled exception: local variable
'tables' referenced before assignment.
