when I receive an encrypted email from one specific person, in both my enigmail setups on different computers, the normal "Please enter the OpenPGP secret passphrase" window repeatedly pops up - for every secret identity (e.g. email adress) i have set up on the respective computer (different numbers on both computers).
This is really strange since the email is only send to one of these identities. After closing every single window that pops up (around 10-20 times) the message is, as expected, decrypted because I typed in the correct passphrase for the mail adress that it has been written to. Once I switch to another email and back the problem occures again. Its really frustrating.
I use Enigmail 1.9.4 with gpg 2.0.28 using libgcrypt 1.6.3. The ubuntu version is 14.04 on the one and 15.10 on the other machine.
Any hint is greatly appreciated. Thanks!
