Possible Bug with Tumblr Importer

I’m getting an error with the Tumblr Importer.

Here are the steps that I took to generate the problem:

Navigate to Tools > Import

Click on Tumblr.

Am getting this error:

“An unexpected error occurred. Something may be wrong with www.remarpro.com or this server’s configuration. If you continue to have problems, please try the support forums.”

I have tried this on two different hosts (ZippyKid & HostGator), as well as on localhost – getting the same issue on all three. Have also got a friend to check it out as well and he’s getting the same issue.

Using WordPress 3.4.2 (also tested with WP 3.4.1 – same issue)

Not sure if it’s a bug or not though so thought I’d better ask here first.

Thanks!
