(intermittent) need to authenticate 3 times before accepted

[Heather Ellsworth]

When at the terminal, trying to file an issue with ubuntu-bug, I was prompted for authentication. Only after the third try was the password accepted.

1. I entered the password correctly and the authentication window closed and reopened very quickly (no error message that I had entered the password incorrectly).
2. Then I entered a bogus password and the authentication window closed and reopened very quickly (this time with the expected “Your authentication attempt was unsuccessful. Please try again”).
3. Then I entered the correct password again and it was accepted.

This happens more often than not, however sometimes I'm not prompted for authentication at all with ubuntu-bug. When I am prompted for authentication, all three tries can be the correct password (no need to have a bogus password entered as one of the tries) and only the third one is accepted.

The expected behavior is:
1. Consistency: ubuntu-bug should either always prompt the user for a password or always not
2. Only one entry needed: If ubuntu-bug is going to prompt the user for a password using apport, then the first correct entry should be accepted.
