I'll have a look into it but I thought I'd drop the error in here first for reference.

This is an interesting bug, I cant reproduce it locally, but it does happen on Travis and on other machines.

[i-like-robots]

Unfortunately my Ruby skills are... best left unmentioned. I'll see if I can grab a little time with one of the proper Ruby guys here.

[PJnes]

I had this error when trying to run without imagemagick installed. It's not mentioned in the ReadMe, but is covered in the OS requirements in the full docs.

[dblooman]

Im still not able to reproduce this, I'll try some different configs and OS's though

[nikglavin]

I encountered this issue when only a single domain was supplied in config and it looks like it was trying to get sizes etc of an image that doesn't exist.

Apologies for the false report

[dblooman]

This will be fixed by #112

[zeroxme]

i'm getting the same error and i can't solve it ... any help!?

[jonnywyatt]

@zeroxme this also occurred for me when running the standard config with a single domain, same as @nikglavin

[wildlyinaccurate]

@jonnywyatt can you please post your exact config and the output of the failing run (including the command you ran)?

In capture mode, Wraith is intended to run against two domains. If you want to compare differences over time on a single domain, you probably want to use history mode.
