I’m having the same issue.
I’ve got about twenty custom content types setup, many with image or media fields. None of them work any more, and haven’t since at least 0.9.5.2. I’m not sure which version it first started in, I think I skipped a couple of mionor updates over the past couple of weeks.
Same result whether I’m adding or editing a post:
-add image/media, the browser pops open, nothing is listed.
-upload, looks like the file uploads, I hit ‘insert into post’ and the image doesn’t show up. Same thing if I use the media library via upload.
Site’s running on a LAMP server, wp 3.3.0 and 3.3.1
I’ll add my details to the bugreport as soon as quickfist has created it.
