Well, that's interesting... looks like it's coming from the JSON library I've used, json-framework.

I'll have to poke around on this a little bit.

The data returned by that URL appears to contain an invalid character:

"PoW" : "Scrypt² PoWT",

In theory, JSON should be either UTF-8 or UTF-16, but that character doesn't appear to be either -- it might be ISO-8859. The JSON library I'm using for pretty printing doesn't even support UTF-16 (see: SBJson/SBJson#115) so it seems like it has a tight coupling on UTF-8... and in fact the line of code that is crashing the entire program is trying to create a new String assuming a UTF8 encoding while tokenizing that character.

Long story short... I think at best I will have to catch the error to prevent the crash but then display the text without pretty printing.

Fixed in Version 1.4.4
