[Evolution] Remote calendar & password

[Mark Stanton <mark stantoncentral co uk>]

Adding an "On the web" calendar seems to insist that there must be a
password, and doesn't seem to cope well with there not being one, or
have I missed something?

The calendar

google com&ctz=Europe/London&pli=1

doesn't have a password, but every time Evolution starts up it presents
me with the dialogue box to enter one. While it does accept a blank
password, it means I have to click the button every time Evolution
starts up.

Is this a "bug"(/feature)?
