Image corruption with owncloud + nginx + php-fpm

[Charles]

Hello,

I can't repeat this issue on FreeBSD with same software version (nginx 
and php). I also tried again with dragonfly yesterday snapshot without 
success.

I don't understand why this corruption is happening, and I have no idea 
how to investigate this.


Kind regards
