Activity Stream broken when CMYK JPEG is attached to an issue

Activity stream dies with: An internal server error occurred when requesting resource http://localhost:8080/plugins/servlet/streams?os_authType=basic&maxResults=100.

See attached image for screen shot of this error.

This appears to be caused by an issue that has CMYK JPEG's attached.

Some exceptions seen in the logs:
