The "Error opening file for reading" is caused by Ubuntu's patch to libjpeg-turbo library. I opened a separate bug report for it to libjpeg-turbo package here: https://bugs.launchpad.net/ubuntu/+source/libjpeg-turbo/+bug/1031718
The error message should be nonfatal, just obscure when it appears in application logs.
