Hi everyone!

Today I installed a Gazebo update package trough the Ubuntu update manager (see extract from the term.log below) and after that my sdf model isn't working anymore.

term.log extract
Preparing to replace gazebo 1.6.1-2~precise (using .../gazebo_1.6.2-1~precise_amd64.deb) ...
Unpacking replacement gazebo ...
Processing triggers for desktop-file-utils ...

ldconfig deferred processing now taking place

When I start Gazebo it says that standard files like empty.world are deprecated.

When I load my sdf file the model falls completely apart with the following messages.

Since sdf 1.4 isn't live, I don't know why it wants my model in sdf 1.4 format. I then tried the gzsdf convert (with success) but the only thing that got changed were the version number and that ' were replaced by ... (more)
