I followed this [tutorial](http://www.magentocommerce.com/wiki/7_-_magento_connect/packaging_a_magento_extension) Package the module which I have developed. Module works fine. When I tried to save I get this error `"There was a problem saving package data"` as shown in the screenshot too.

Documentation says *You will have ”There was a problem saving package data” when you save the extension if there is space inside the module name.* But as you can see there is not spaces in the module name.

What could be the issue? How can I fix this?
