i need a help on to list the package names in the salesforce organization

I can successfully create an object and tab using the metadata API.  However, the tab isn't visible by default (uh), so I have to change the user profile information to correct.

However, when I try and do this using the update() method I get
UNKNOWN_EXCEPTION
An unexpected error occurred.

Can you tell me how to do the tab visibility update?  Am I doing something wrong?
