That is an error in WordPress core, it doesn't give enough information for me to know the cause.
The patch that I had you install would have removed all translation issues from the framework, so it's likely that one of the plugins is causing the problem. You can find out which one by deactivating the plugins one at a time until the error stops happening. If the plugin causing the problem is a Shape5 one, let me know, and I'll do everything I can to fix it.
