i386 -> amd64 breaks a lot

[flobee]

Hi

The good: The addon works really good.
Thank you that passwords still in sync but: When changing the OS without /home (i386 to amd64) all passwords seems to be lost.
This [1] was the first adress to ask for

Now i would like to infom you and ask how to solve it for the future!?

My trouble report:

Solution aftersome hours including backup recovery for analysis... Disabling the plugin brings back the passwords for firefox. But what about other passwords? e.g. Machine passwords or thunderbird passwords if the keyring db doesnt understand changes of the OS.

Kind regards
Florian
