Created attachment 661270 [details]
The mock config file i was using at the time of the bug.
Comment 2 Josh Boyer 2013-01-02 14:18:20 UTC 
Is this recreatable?  The fff2f2f2fff2f2f2 is rather suspicious, but I have no idea what would cause something like that.
Comment 3 Antonio Augusto Santos 2013-01-15 02:47:24 UTC 
This bug can be closed. I've traced my problem back to a fault memory stick.
Thanks for the support.
