Check if you have enough free memory by telnetting to your box and running "free" command. I have this problem on my Duo, 128MB RAM is very little these days. Especially in my case with transmission and nfs server running, plus streaming TV channels to my XBMC on RaspberryPi. I found out that even 128MB swap file I created is not enough . I know, I know, I'm really abusing my poor old satellite receiver...

I think I had the same problem on Vu+Duo. Once the plugin is enabled, the box is in loop of restarting enigma2 with GSOD. The easiest way to solve this is to reflash, but there is another way - while your enigma2 is restarting, you can still ftp/telnet to your box and simply delete the plugin directory. If I remember correctly, the plugin directory should be located in

/usr/lib/enigma2/python/Plugins/Extensions

look for a directory named vfdpermanentclock or something similar and delete the directory. Enigma2 should start normally now and you can remove the plugin (actually just the plugin reference, the files you deleted already manually) in a normal way.
