Attachment: gif_firefox.png

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.112 Safari/537.36

Steps to reproduce:

We are running Typo3 (7.4.0) & GraphicsMagick (1.2.7). We upload PDF files and display processed versions (.gif extension) on the frontend.


Actual results:

In Firefox the image seems to be broken, in all other Browsers (even Internet Explorer @ 11.0.9) the image is ok. In Mobile Firefox the image is ok (on ipad).


Expected results:

The image should be displayed the same way in all browsers.

This is fixed on nightly, so I think this is likely the same bug as bug 1234077 (which was fixed by bug 1247152).

Thank you!
I tested the 48.0 Nightly and there it works!
