Yes you should upgrade to 1.9.8. Otherwise educate yourself to avoid this bug:

Yes, upgrade to 1.9.8. Also, double and triple check spelling when you write your seed down.

But also remember: (Because there is always possibility of malware on your computer that may alter things.)

Be familiar with your wallet. Know how many bitcoins are in it. Know about how many times you've used it. Know what kind of labels you have on it.
If a piece of malware replaced default_wallet with a watch-only wallet to an attacker's electrum wallet, would you be safe? Would you recognize that it isn't your wallet?

The bug in 1.9.7 is a bad bug, I understand, and I don't want to blame victims. BUT I think that people need to be diligent when dealing with money on their computer.
Especially on a computer that has touched the internet, double check everything, always.
Anyone who hits the wallet restore bug has about 3-5 huge red flags they should notice... restoring from seed should NEVER create a watch-only wallet, being one of them.

hi... i done a test on my 1.9.7 unbuntu..

which bug do u mean? i purposely type 1 out of my 12 seed wrongly in spelling and it gives me an error.. i dont see a watch only wallet appear..

what did u do to see a watch only wallet?

See here:

You can restore using hex digits too. So type in any 31 hex digits instead of 32 and see what happens.

Some combination of mnemonic words must also be triggering this bug. But it is most easily reproduced using the seed in hex.

Ic.. so if i see on the top of mine has no watch only wallet means i am on the right track right?
Which means i key in the right seed.

Anyway how to transform 12 word seed to hex?

Yep. Addresses should also be familiar ones that you've seen before. The same goes for transactions and balance.

Anyway how to transform 12 word seed to hex?

You can use the getseed command to see the seed in both hex and mnemonic form. Or you can use mnemonic.py to convert any arbitrary seed from one form to another.

Electrum getseed via command line/shell:

Code:

electrum -w /path/to/wallet/file getseed

mnemonic.py: First find mnemonic.py on your file system then run this:

Code:

python /path/to/mnemonic.py word1 word2... word12
