Title: Bug Report: Private key not Yielding Correct Public Key
Post by: SnowDog2003 on September 09, 2013, 05:14:42 AM
This is a bug in the development version 1.9. It may, or may not be, a problem with the current release version.

Here's a private key that I'll no longer use:

In every other wallet, it will generate this public key hash:

1BbJHQStkpMcoqJ3ysZRV6HNpe3bGooiUK

In Electrum, it generates this public key hash:

This is not an isolated case. I saw this yesterday with another private key, but I want to keep that private key and do not want to disclose it. I did, however, test a specific case:

1) I ran 'importprivkey('<my key>')' from the command line of the Electrum Wallet.
2) I noticed that the public key hash was incorrect.
3) I sent funds to the incorrect public key.
4) I then tried to use the public key in the Electrum wallet by setting it to 'Prioritize', and then using it to send funds. The transaction failed completely with an error. I am not sure, but I believe the error was 'None Type', or something similar.

thanks for the report. it looks like a recent regression in git master.
1.8.x versions are not affected.
