Two versions of an answer -- one makes Q2A throw 500 error

Question

Ok, this is wild.

If I put in this answer (without quotes)

"Firstly great presentation of course. Secondly I have to say after viewing the content the area that I liked the most was relative to selective pruning. For some reason I figured that selective pruning was related to suppressing concepts that were less important and replacing them with newer or more recent ones that were related to the mental concept but I now see it is a link that extends from the base of the general idea. For example like you mentioned relating furniture to chair ect. However the visual presentation helped a lot with understanding Thagard’s concepts versus just reading the text."

I get a 500 error

However, if I change "from" to "farm", it works

The raw string is how it appears in the database -- no html formatting.

UPDATE 1/31/13

OK, check this out: I can shorten from the beginning as well -- this also reproduces the error

selective pruning from the base of the general idea.

Notice the pattern: select * from X?

Is the answer getting run through SQL, which is generating the error?

Seems to work fine here!

@Scott: He is using 1.5.4 not 1.6dev :)
But yep, I cannot see the error...

PS: And how do you get the idea to replace one word out of 100s to find the error?

---

I added a sentence at a time. It would work until I got to "from". First I thought it was a limit on length, but when I changed the word it worked.

I just checked again by copy/pasting from Scott's reply and it still didn't work. Can you suggest a way that I could debug/give you more information on this?

Is that seriously what's going on?

OK well I tried on my own site and it works fine.
