How can I recover my MultiBit HD wallet words? I have problem with MultiBit HD. Its balance changed to an unconfirmed transaction just like in this bug report.

It appears that I need to use my wallet words to recover the balance, but I have lost (totally lost, there is no chance of recovering) the wallet words. 
But given that I've got list of all possible words used in MultiBit HD and my wallet can I use it in some cracking program to find my words and their order in which they occur?

I do not have any experience with brute force or cracking, I'm just a regular, lame computer user.
If you have both your wallet file (named mbhd.wallet.aes for MultiBit HD) and its password, you can use this tool to extract its mnemonic sentence/seed.

Note that the terms "brute force" and "crack" weren't the right ones to use, you're simply decrypting the wallet file. David's answer is correct in that you can't brute force a seed from scratch, but luckily that's not what you need to do here.

(Also, be sure to write your seed down somewhere once you have it! If you had lost your wallet file, you would have been out of luck...)
