Thanks. These are classified as non-error warnings by graphicsmagick itself and I don't believe the functionality is impacted, though I'm not entirely sure. I believe the cause is the source media downloaded from the remote server.

Unless these messages are truly spamming the WARNING log level it's probably best to not demote them to DWARNING. I'm leaving this open so more can be learned about these messages and if anything can be done to mitigate the issue.

For all intents and purposes of a matrix server the message is harmless (and useless): it notifies us that the color space of the original is fucked and whatever we do about (eg. convert it or resize it) it will result a similarly fucked up color space, eg. the image will not have perfect colors, just as the original.

It is not an annoying amount right now but probably should not be shown later in the final version, since it's rather a DEBUG level message. For now it's okay (I just didn't have them because graphicsmagic wasn't installed).
