The most likely cause for this problem to occur is some missing libraries which are needed for the RC plugin proper functioning.
So, please check if the following libraries are present in the current Linux installation?
If they are not, running the following commands should install them:
sudo apt-get install libgtk2.0-0:i386 libidn11:i386 libglu1-mesa:i386
sudo apt-get install libpangox-1.0-0:i386 libpangoxft-1.0-0:i386
After that, restart the linux box and try to take it by Remote Control again.
The Remote Control session should succeed now.
