rqt_image_view and ros2 throws exception

edit

I have problem in ros2 with rqt_image_view. Starting it and pressing refresh gives:

tompe@tpexps:~$ rqt_image_view 
terminate called after throwing an instance of 'rclcpp::exceptions::ParameterAlreadyDeclaredException'
  what():  parameter 'mode' has already been declared
Aborted (core dumped)

Same issue when starting two rqt_image_view and trying to show different image topics. Also in rqt adding two image_view plugins will give this crash.

And showimage stopped working for me. Any idea why this can happen? So I cannot fins any way to display two image topics at the same time...
