Catalogue generate fails

[KABx]

I have just upgraded to version 0.9.4

every time I try to generate a catalogue, it fails with the error below. Doesn't seem to make any difference which books i select or de-select.

last time I was on v 0.9.2 and it worked fine. i've not changed any of my catalogue settings (shown in attached jpg).

can anyone help?

I won't be able to fix this bug for about a week - I'm traveling without my development machine. You can revert to the older version or wait until the fix is in place.

thanks - i wasn't sure if it was a bug, or something I had done.

I'll hold out for the fix

[GRiker]

Fixed, will be in the next release.
