Image upload - HTTP error

Unable to upload some type of images, because crunching error.

Reproducation: Try to upload attached png image (SC20120611-160917.png), to wordpress site (3.3.2). I try it all of my wp sites, and fresh installation (without plugins). The upload progress aborted (HTTP error).

If you convert the png file to jpg, the upload and crunching was succeed (there is no configuration errors i think).

I try some workarounds too, but doesn't help (this is not an individual problem i think): http://wordpress.org/support/topic/http-error-on-image-upload-still http://wordpress.org/support/topic/flash-uploader-logs-out-during-crunching-phase?replies=19

This error affected 3rd party tools (like android wordpress app).

  • Component changed from General to Upload

Tested the attached image on both 3.3.2 and 3.4-RC4, could not reproduce the issue.

2-year old workarounds for the Flash uploader probably no longer apply, since there's a new file uploader now (#18206) which uses HTML5 first and should fall back to Flash only in IE if Silverlight is not installed.

I think this problem php/apache issue. On local installation i cannot reproduce this error.

The isp apache version always generate HTTP error with any png file upload.

The isp server phpinfo available here: http://voji.hu/phpinfo.php

Just out of curiosity, are you using WP_Smushit?

The Smush.it API has been really flaky lately, and if it fails all you see is a generic HTTP Error.

  • Version changed from 3.3.2 to 3.4

Today i update my productive sites to 3.4. The problem still exist, but the HTTP error disappear (after png upload, the progress bar freeze with "Crunching…" state, and no thumbs generated).

I no use WP_Smushit (in my productive installation use only official plugins + Google Analyticator, and Google sitemaps).

I created a clean wp install on isp server, for testing purposes (currently waiting for dns modifications to apply).

The clean install is up and running, but the error still exists.

Apache error, php_error logs are empty.
