It's not necessarily that you screwed up. It might be a rare, latent bug somewhere. It can be hard to fix bugs that you can't reproduce for yourself.
Also, I just tried it myself and can't reproduce it either.
I'm just wondering, does this log mean anything to you? Probably nothing. I see I can upload images in tinymce using zp button. It works.

Oh, you know, a photo through tinymce. The other uploads went fine.
Not important. I thank you for being there for me. We can probably close this now. I don't think we'll be able to figure out the problem with uploading when clicking on the tree icon in tinymce.
This error indicates that somewhere a URL was created that had the form //advanced.html. Given that there was no such advanced.html file found on the path zenphoto would treat this as a request to load an image of that name.
Do you use the class-textobject plugin and have html "imges"?
Well, I have an suspicion now. "advanced" is the tinyMCE theme that is used for zenpage items. Now Safari and other webkit based browsers have a bug that sometime displays js source code where it should not. It looks that this maybe happened with this form. In that case there is nothing we can do than to suggest to use Firefox...
It could also be a folder (or file) permissions problem that does not let the WEB browser access this file. The mod_rewrite rules will assume the file is an "image" if it is not "present" on the server.
Try disabling mod_rewrite and see if the problem goes away.
