Downloader errors after upgrading to 1.9.1.1

[gdhnz]

After upgrading to v1.9.1.1 form v1.9.1.0 via the mage script, I got the following errors

Warning: array_combine(): Both parameters should have at least 1 element in /var/www/html/magento/downloader/lib/Mage/Connect/Rest.php on line 239
Warning: ksort() expects parameter 1 to be array, boolean given in /var/www/html/magento/downloader/lib/Mage/Connect/Rest.php on line 240

these 2 lines refer to the following

$package = array_combine($versions, $stabilities);
ksort($package);

Looking at Magento afterwards, I can't see anything obviously wrong. It's reporting I'm now on 1.9.1.1 and everything appears to be ok.

I am receiving the same problem with same error notification ofter upgrading from 1.9.1.1 to 1.9.2.0

I get one pair of errors for each up to date module.

Any solutions found for this?

My systems log file is full of this error and my authorize.net credit card form doesn't appear.
