Bug#678682: ubuntu-dev-tools: requestsync fails to authenticate: IV must be 16 bytes longs

Package: ubuntu-dev-tools
Version: 0.143
Severity: normal

Dear Maintainer,

I'm trying to request a sync of my mail-notification package, using
requestsync. After entering my keyring password authentication fails
as follows:

% requestsync -s mail-notification
Please input your password for the keyring
Traceback (most recent call last):
