livecd-create error message

[Dennis J.]

Hi,
I'm trying to build a live-cd so I can test the latest ATI driver revision 
for an active bug I opened a while ago [1]. For that purpose I created a 
Rawhide VM on my F11 host because apparently one cannot build a Rawhide 
LiveCD on a F11 system.
The problem is that once the livecd-creator has downloaded the 
primary.sqlite file I get the following error [2]:

Error creating Live CD: Unable to download from repo: database is locked

I tried different mirrors and a F12 release repo but always get the same 
message. What is livecd-creator trying to tell me and how can I get it to 
build the liveCD?

Regards,
   Dennis
