Hi everytime I try to get in segmentation mode on my dataset it gives an exception and hangs. I can reproduce it everytime on my dataset

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

and I have four videos (mp4) and one audio (wav) file.

I tried to load the videos and the wav without the tamplate and it works fine, it started to hang as soon as I added the controlled vocabulary. it hangs when I switch from any of the modes to the segmentation mode, If I add the controlled vocabulary while in segmentation mode it works fine.

Any workaround, idea, patch ?

Thanks
