What happens when you upload a file via Admin CP > Maintenance > Diagnostics > Upload

I'm trying to avoid turning off all add-ons, in order to prevent further service interruptions.

Here are the results of the diagnostics:

file_uploads: On
open_basedir: None
safe_mode: Off
upload_tmp_dir: /tmp
upload_max_filesize: 2.00 MB

No errors occurred while opening the uploaded file for reading.

Just disabled all add-ons by editing the config file and adding this:
define('DISABLE_HOOKS', true);

Saved the file, cleared browser cache/cookies, logged back in, tried uploading a new custom avatar, and the custom avatar shows up as a broken image file. Doesn't look like it's a problem with add-ons.
