every time i select an ogltrans effect in impress 4.0 crashes

I have installed ogltrans for Libreoffice impress , through synaptic, but cannot get it to function, as soon as i select a transition . it crashes, have removed and re-installed couple of times but no diff. I had the same problem on my laptop , but fixed it by un-checking the "use hardware accelerator" box, that does not work on my desktop. The difference is -laptop uses Sun Microsystems 1.6.0_27 and desktop is Oracle 1.7.0_25, I also believe there is a fault within the Charts option as it WILL Crash every time I start using it while creating presentation, but that is another issue. Using Ubuntu 12.04, and yes I am a newbie. Any non technical answer would be apreciated.
