...making Linux just a little more fun!

This is, hands down, the single dumbest bug report I've ever seen: http://code.google.com/p/tesseract-ocr/issues/detail?id=337
I'm kind of reminded of the usability thread, because whenever I see a dumb question on the Tesseract list, or in the issue tracker, it's always a Windows user.
But mostly, I'm just wondering: can anybody think of a valid reason why anyone would want to OCR a CAPTCHA?

I did say 'valid'... My answer was: That's a CAPTCHA, which BY DESIGN cannot be read by OCR.
You've betrayed such a complete misunderstanding of everything you've cared to mention - digits are numbers, not letters - that I wouldn't know where to begin, usually, but as I can't think of a single valid reason why anyone would even want to OCR a CAPTCHA, I guess I don't need to.
In fact, the only people I can think of who would want to OCR CAPTCHAs are spammers, which is what I'm going to consider you to be. Status: Invalid Labels: spam

OCR is one of the applications of computer vision.
The computer vision and artificial intelligence guys are extremely interested in figuring out whether CAPTCHA's are truly beyond the capability of "automated" cracking. In some cases CAPTCHA's have been cracked by programmes. For example,
http://www.cs.sfu.ca/~mori/research/gimpy/
Remember that CAPTCHA stands for:
Completely Automated Public Turing test to tell Computers and Humans Apart
So it is an attempt to have a computer generate a Turing Test which another computer cannot solve. If it is indeed possible to do this then AI would have failed!

My linusability project specifically excludes MS users and MS worshippers, for this very same reason. I am also deliberately avoiding users who want to dual boot Linux with MS-Win. Like trying to use a buffalo to propel a jet engine. . In fact, I come across many more disgusting ones than the person who wants to OCR a CAPTCHA.

You said it yourself: spammers. I think that's a 100% lock.
They were probably hoping that you, or whoever else responded to their "bug report", were stupid enough to show them how to make it work (which involves the assumption that it can be made to work.) Looking like an idiot against a chance of learning how to crack CAPTCHAs? Any spammer would take that bet, double-quick.

...at either one end or the other, inescapably.

[laugh] You could do it; it would just be a very, very slow-moving jet engine. I suppose you could always use it as a vegetable cart...
It reminds me of the story of a marine railway in South Africa, not all that many years ago, where the shiny multi-million dollar carbon-fiber- and-Kevlar racing boats were hauled out by elephants.

Yeah, but I think somebody engaged in legitimate computer vision research would be aware that you need more than a single sample to perform training, and, even if they weren't, would have paid enough attention to the training document to have read that.

Mostly, I've been second-guessing my reaction (it has been brought to my attention quite a lot recently that I can be quite harsh in my responses). I asked on an IRC channel too, they all came to the same conclusion...
<jimregan> I don't want spammers coming to me for free help <jimregan> well <jimregan> one exception <jimregan> assisted suicide
A lot of people use Tesseract for tasks for which it wasn't designed - most of the people who are vocal on the mailing list, in fact - including licence plate recognition, business card recognition, etc.
So it had been at the back of my mind that, at some stage, some spammer would happen along. What particularly disgusted me was that I had been prodding at the particular feature the spammer had requested earlier in the day.
