[Plugin: WordPress HTTPS (SSL)] URL surrounded by parenthesis loses end parenthesis

Using latest wordpress 3.4.1 with latest https plugin 3.1.2.

I have some in page styles that look like this:
url(“https://www.wordpressmembershipuniversity.com/wp-content/plugins/optincrusher/images/x-runner-duo-blue.png”) repeat-x left bottom;

When I load the page over http this happens:
background:transparent background:transparent url(“https://www.wordpressmembershipuniversity.com/wp-content/plugins/optincrusher/images/x-runner-duo-blue.png” repeat-x left bottom;

You can see that the end parenthesis is missing. Disabling the plugin corrects this error.

How can I correct this?
