skypetab prevents shutdown

[sbarmeier]

After the last update (June), a running skypetab prevents ubuntu 12.04 from shutting down. All other open applications are terminated by the shutdown process. Closing skypetab ubuntu shuts down as normal.

It happens when "Minimize on close" option is enabled. Ubuntu just fails to close SkypeTab. Workaround: disable the option.
