gzclient crash with heightmap

edit

Hi

I obtain an ogre exception each time I try to use an heightmap e.g., using

gzserver -u worlds/heightmap.world

the gzclient crash with the following output

Qt has caught an exception thrown from an event handler. Throwing exceptions from an event handler is not supported in Qt. You must reimplement QApplication::notify() and catch all exceptions there.

I'm running Gazebo 1.4 by repository binary packages on a xubuntu 12.04 in virtual machine. In particular I've tried both vmware and virtualBox, both with the same results.

I've found online other thread about similar problems, but I can't face a solution for my one. Any suggestion? Avoid the usage of virtual machines? Compile and install from source code?
