[wp-testers] gobbledygook in html when uploading image

[kimsch]

On latest (also on 3.1.3 earlier at same site) I have been getting some
gobbledygook that keeps coming back when switching from visual to html
editor. 

When I upload the picture everything is fine in the gallery, the photo is
there, sizes are fine, etc.

In visual there is no image there.

In html there's this:

<a href="http://***.***/***/***/***/***/1055.png"><img class="alignnone
size-medium wp-image-100 gfggwnleiigodimkxikl" title="1055"
src="http://***.***/***/***/***/***/1055-300x250.png" alt="Shrug"
width="300" height="250" /></a>

If I delete the gobbledygook and save, it looks fine in html, but if I
preview the post or check the visual editor there is no picture. When I get
back to the html editor gobbledygook is back.

If I try straight from html it's originally this:

<a href="http://**.***/***/***/***/***/1055.png"><img
src="http://***.***/***/***/***/***/1055-300x250.png" alt="" title="1055"
width="300" height="250" class="alignnone size-medium wp-image-100" /></a>

I save and switch to visual, no picture. I switch back to html and it's as
above with the class first and the gobbledygook.

In neither case can I see the photo on preview or view post.

I had uploaded 16 photos on different posts prior to this. Oddly enough it's
only happening on Firefox for me, not IE9, Safari, Opera, or Chrome. I
closed and reopened Firefox and even rebooted. 

Any ideas?

Thanks,

Kim
