[Flub]

I just bought a couple of drm'd mobipocket books from Fictonwise (As I've done a lot in the past). I removed the drm in ways we aren't supposed to talk about and fed the resultant files into Calibre for conversion to lrf. Instead of getting lrf files as I usually do I got this error log instead.

I then tried epub and got this result

This is with version 0.4.133 of Calibre although initially I was getting the same problem with an earlier version. Is there anything I can do to get this converted?
