Error on Wordpress 3.2.1 file upload

[DoomTay]

Describe the bug

1. Set up a local web server
2. Extract Wordpress 3.2.1 to it, and set it up through the "installer" on the front page
3. Extract Ruffle to "wp-includes/js/ruffle"
4. Replace "wp-admin/media-upload.php" with the "media-upload.php" file from this ZIP
5. Navigate to http://localhost/wp-admin/media-upload.php
6. Alternatively, extract the above ZIP and navigate to http://localhost/standaloneflash.html
7. Select an image to upload

This yields the error message below

Uncaught TypeError: fileObj is undefined
    fileQueued handlers.dev.js:18
    queueEvent swfupload.js:725
    executeNextEvent swfupload.js:745
    queueEvent swfupload.js:730

    anonymous core.ruffle.dcfa3c9d8d109b5ae831.js line 1 > Function:3

Expected behavior

An image would be listed, indicating a successful upload. In the case of "standaloneflash.html", there should at least be the message "HTTP error." on the page

[Lord-McSweeney]

This seems like a problem with the libraries (specifically swfupload.js) that you're using, not with Ruffle. Have you tested it on a Flash-enabled browser, such as Pale Moon?

[DoomTay]

I did test it on Basilisk and it works just fine there

[DoomTay]

Might also be worth pointing out that when clicking the button in Firefox, I'm treated to an overlay that displays a form for uploading the file(s). Not so in Basilisk; there, a file picker opens immediately.
