rqt_rviz OGRE EXCEPTION Zero sized texture

edit

Dear all.

When I run the command rosrun rqt_rviz rviz and then I try to load a map then rviz crashes with the following error:

terminate called after throwing an instance of 'Ogre::RenderingAPIException'
    what():  OGRE EXCEPTION(3:RenderingAPIException): Zero sized texture surface on texture MapTexture0Downsampled face 0 mipmap 0. Probably, the GL driver refused to create the texture. in GLTexture::_createSurfaceList at /build/buildd/ogre-1.7.4/RenderSystems/GL/src/OgreGLTexture.cpp (line 406)

Then, If i do the same with the command rosrun rviz rviz rviz does not crash, it shows the map.

I think it is a problem in the rviz plugin, but to be sincere I have no clue.

Any help will be appreciate it.

Thank you in advance
