Twice I've run the scraper and it crashes midway through the import. I think it was at 65/118 on my last try.
Safari Version 8.0.8 (10600.8.9)
OS X Version 10.10.5 (14F27)
Here is the crashed thread from WebKit:

[LB-23] LB Scraper crashes Safari page
You just caught me before I upgraded my computer. I ran it several times and no crash. This bug looks fixed, though we'll see after I upgrade to Safari 9. 
We recently released 1.3 of the scraper, with which we are unable to reproduce the safari crash.
Another v1.2 crash:

Thanks for the update, it looks like we have some more work to do on this issue.
I got this crash the first time I ran it, the second time it went all the way through.

We've made some changes to the submitter to have less work in progress at once. Can you try again?
This crash happened on the version without the starfield.

I just ran a few imports on OS X 10.11 with Safari 9.0 (11601.1.56). No crashes. I think we can close this bug now.
