Comment (by Dvaer):

 Thank you everyone for working on this. I've experienced the same issue on
 2 client sites now. Both running on WordPress 4.5.2 and on the same host
 (Site5). In our case the functions.php fix suggested by @smashingjay
 solved the problem in both cases.

 From phpinfo():
 PHP Version: 5.5.34
 Imagick Version: 3.3.0RC2
 ImageMagick Version: 6.7.9-10 2013-08-29 Q16
 memory_limit: 128M
 max_execution_time: 30
 max_input_time: 60
 upload_max_filesize: 128M
 post_max_size: 128M

 This wasn't an issue on these 2 sites before. When initially
 troubleshooting I turned off all plugins, which made the image uploads
 work again. But then re-enabling plugins one by one I couldn't isolate a
 single plugin as causing a conflict. It was more that after 3 or 4 plugins
 were active again, the issue reappeared. But it didn't seem to matter
 which plugins.

 Other client sites on the same server with very similar setups are not
 having this problem. The common thing with these 2 sites was that they are
 both running a child theme. I'll check some of our other sites to see if
 that might have anything to do with it and report back here.
