Description:
if one of tables is crashed (MYD or MYI file corupted), MA displays message:
-----
Error while fetching Schema Table Status.
MySQL Error Number 1016
Can't ope file: '....table name...MYI'. (errno: 132)
-----
Catalog is unacessible and cannot be used Maintenance functionality.

How to repeat:
Edit MYI file to be corupted
In MA go to catalogs and click on schemata with corupted table
MA shows message above.

Suggested fix:
Display warning message (short description for all problems)
Display list of tables with marked corupted tables (+ message returned from MySQL server)
Grey-out button 'Edit table' when corupted one is selected.

I cannot repro this behavour with latest versions of MySQL Server/Administrator. When .MYI or .MYD is broken, table is shown and can be checked/repaired. The only issue that I have noticed is that when .MYF file is broken MA doesn't show the object (table or view) on the catalog page as the server cannot tell what it is - table or view, like this ('broken' was a table):

mysql> show table status \G
