Press This: Problems with posting when image upload path is invalid

[awayken]

I had a strange experience. I was using the Press This bookmarklet to write a post based on another blog article. I chose an image from the article to show up in my post. NOTE: I was not uploading the image to my webserver. I was letting Wordpress perform the equivalent of an <img src="...

I hit Publish, and I got an error message stating that my upload path was invalid. It was a nicely formatted Wordpress error. I checked my blog, and the post had actually published, though without content. It had the title I'd used and the categories, but it was a blank post. My upload path (wp-content/uploads by default) had gotten changed to something invalid. I could only post from Press This correctly again after I changed the upload path to a valid one. The oddest part of this is that I wasn't trying to upload anything at the time.

NOTE: I have been unable to recreate the issue. I've tried changing my uploads path to paths that don't exist and to paths that don't exist and do not have write permissions on the folders and neither have reproduced the error. So, maybe it was just me those two times I had a problem.
