Also see bug 66349 about proc_open() and thumbnail generation.

safe_mode was mentioned on support desk already, but I'd be more interested in getting to know if those functions are listed in "disable_functions" in php.ini.

From my current interpretation of things, this ticket will become WONTFIX / INVALID.

@Andre: totally Agree!

Someone tracked this issue down to something introduced in 1.23wmf12.

I'm one of this users who has problems with uploads after the upgrade (http://www.mediawiki.org/w/index.php?title=Project:Support_desk&offset=20140613133023&limit=20#image.2Ffile_upload_broken_after_upgrade_from_MW_1.19_to_MW_1.23_43912)

We are running our own servers. So I can help you with debugging and testing out new code.

As I wrote in the support desk question, my Apache2 is running with mod_chroot enabled and everything is working fine besides the upload (and I can't find any error or warnings in the logs or the debug output.)

popen() would only be used with 'parallelize' set to 'implicit' or 'explicit'. The default is 'off'. Did you change the config from defaults?

Ah nevermind, I think I see what's going on here.

I applied this patch now to my installation. Fileupload seems to work now.

All patches merged (or abandoned) hence assuming this is FIXED.
Thanks everybody for helping tracking this down.

The last comment does not make any sense, and I have already explained in bug 67744 how to find the patch / code fix for this problem.
