I run an SSL-enabled site (https://www.eviscerati.org) and ever since the last update my visitors have reported that on pages where service links are enabled, they get browser warnings that the sit may be unsecure. It took some searching before I could determine it was actually a Service Links problem, but I believe the problem has to do with the graphics used for both the links and the widgets. Some are being pulled from other sites, and they don't use "https" when doing that pulling. Linking to a remote image without using https will cause every browser out there to report that a certificate-enabled site might have been compromised.
I've been using Service Links for a while, and I didn't start getting these reports until very recently, so it appears this was introduced in the update on the 10th. When I'm pretty sure it's a problem with the module because when I disabled it the warnings went away.
