2012-12-03 14:37:11 -0500 asked a question compressed_image_transport runtime error

Hi. I am getting the following runtime error when trying to output an image through the image transport mechanism. I am not even attempting to send compressed imagery through the image transport mechanism. Any ideas? Once in a while, I don't get this error, but I cannot correlate the success with anything I am doing.

I had this problem and localized it to the libeigen3-dev version. The ros install was expecting an older version. I just reverted to the older version using the force option in the Synaptic Package Manager and then did the install of ros-fuerte. It worked after I did the downgrade!
