I have the Bitcoin Client "MultiBit" Version 0.5.9 (most up to date i think).

I transfered bitcoins from mtgox to my wallet. no problem.

now I have 0.5762188 BTC in my wallet. I tried to send these (ALL OF THEM) to another wallet. I quickly noticed that there is a fee (or call it a fine) I have to pay. If I go to settings it says "Fee: 5 BTC". I changed it to 0.0001 which I found out is the lowest. When I go back to the Send Coins tab it changes the fee to 1 BTC. Wow, cool.

the wallet address is: 151Z8BwDCJnx1DKw1fDAu8tgjG6gTp5xf8

yes, it was a single transaction from mtgox to my wallet (yesterday). I have installed the MultiBit client yesterday.

Great, so we can now see here in this transaction:

that MtGox sent 0.5762188 BTC.

Oh, wait, I just remembered reading about someone else having this issue recently. I'm almost certain this IS a bug in the version of MultiBit that you are running. I'm not sure, but there may be a patch available. I'll look and see if I can find the discussion, and if so I'll post a link here.

The issue was that a recent version of MultiBit wasn't properly handling situations where the comma and the decimal point aren't used they way they are in the United States. I suspect that in German, a comma is used instead of a decimal point, right? Hopefully, I'll be back shortly with a link for you.

Apparently no patch yet. According to the following discussion the only solution at the moment is to install version 0.4.22:

I have 10.8 BTC on my MultiBit wallet. I want to transfer my BTC to my account at btc-e.com market. But MultiBit wants me to pay comisson 1 BTC for transaction. Even if I try to transfer 0.1 BTC.

the issue solved by downgrade to version 0.4.22! 0.4.23 must have been buggy(((
Thanks fsb4000!

This was a bug to do with parsing of the transaction fee when you have a locale that uses a ',' as the decimal separator.
It is fixed in release 0.5.9 (https://multibit.org/releases.html).

You can just set the transaction fee in the Preferences tab. Press 'Apply changes' to save the new amount.

Still not fixed in 0.5.9 version.

It sounds like you either need to change your locale to somewhere that uses a '.' as the decimal separator, or you need to install 0.4.22

Quote from: nicofan on May 01, 2013, 06:27:27 PM

ok, I'll try to downgrade to 0.4.22.

What do I have to backup before I uninstall MultiBit?

In the original folder where I saved my wallet, are the following files:

walletname.info
walletname-20130430233733.key
walletname-20130501195242.wallet
walletname-20130501195442.info
walletname-20130501195442.wallet
walletname-20130501195442-20130501202028.wallet

Do I have to keep all these files and use them with version 0.4.22?

I also have to say that I only have ONE wallet, why are there 3 of them. Which wallet should I open with 0.4.22?

This is so confusing.

I'd create a backup copy off the computer (perhaps to a USB drive) just in case of disaster. Perhaps backup all the files, and then figure out which of them you actually need to recover if the upgrade doesn't behave as expected.

Another option would be to find out how to export the private key for the address before you do the "downgrade". You could write (or print) that private key to a piece of paper. As long as you have the correct private key, you'll be able to regain control of the bitcoins even if MultiBit becomes completely unusable for you. That private key can be imported into another wallet, or swept back to MtGox if necessary.

I uninstalled version 0.5 and installed 0.4.22 and now I get this:

"com.google.protobuf.InvalidProtocolBufferException Message missing required fields: key[0].type"

I can't open any of the 3 wallets listed above, I always get this error. When I try to import the key it says "no wallet selected". I can't open the wallets because it doesn't find the key, and I can't open the key as long as I can't open/select a wallet. nice.
