"Illegal Instruction" when using "image_view" with theora.

edit

Hi,

I'm using latest ROS electric with Ubuntu 10.10 (kernel 2.6.35-27-generic).

When running:

rosrun image_view image_view image:=/foo/image_raw _image_transport:=theora

It returns nothing but an "Illegal Instruction" message.

This error appears to any subscribed topic with sensor_msgs/Image message type, even from usual nodes like usb_cam and gencam_cu.

Also it works well with compressed and raw transport.

From reading the core of image_view with gdb:

    Program terminated with signal 4, Illegal instruction.
