"wallet check passed" : true
}
dude, i have extensive time dealing with this problem. its a windows 7 issue that has nothing to do with coins being stuck. just certain tx hashes freeze wallets from time to time on windows 7. i've found that i can import them on windows xp sp 1 with no problem. trick works on vista too. haven't tried windows 8 yet. worth a shot.
in the computing world these are known as uncaught exceptions, ie. an block or tx hash that doesn't meet the define rules(chainstart/target size/etc.) but is still acceptend in the chain.) it happens all the time in litecoin variants and mostly goes unnoticed. it happened a on bitcoin less than a week ago and froze the electrum servers. minor inconvenience, should be able to work around it
