tried alpha on other computer

Hi Lucas

I just got my own computer back.
( old ) Acer desktop with 3 Gb ram

Inserted DVD and booted up.
Choose default language and keymap
Enter ..startx

During bootup to final stage, I got following messages.
Error:nepomuk file
could not find mime type:
-inode directory
-inode,blockdevice
-inode,hardrive
-inode,socket
-inode,fifo
-application x-shellscript
-application x-executable
-application x-desktop

press OK

could not find mime type:
application/octed-stream

press OK

Booting up to a total black screen.
However, the task bar is visible and from there one can change//import a 
wall paper

The rest looks standard........... so far.
Didn't have more time today

Just to let you know.

Tony
