Do you have anything more in the verbose log around this line?

[Dan Mills [:thunder]]

Thanks.  My guess: you synced data up with one passphrase, but are trying to decrypt it now with a different one.

If you aren't sure what passphrase you used, try this on *both* computers:

1) Go to the weave prefs and then the advanced pane.
2) Delete the login information and the server data (but be careful not to delete the local data).
3) Restart Firefox.
4) Try to log in, that should take you through the setup wizard.  Make 100% sure you are using the same encryption passphrase on both computers.

If I'm right, the above should work.  In that case the real bug is that Weave has no safeguards against typing in an incorrect passphrase (!).

Comment 4

[dominique.gonzalez]

Funny! But it is not an incorrect passphrase "bug".
I was sure that I did no mistake, but I made the test with a simpler passphrase.

With the same result.

Comment 5

[Stefan Max]

I have the same problem. The passphrase is 100% correct, I tried multiple times.

Initial data transfer works fine, but each successive sync fails with above error.

My log looks pretty much the same, the "invalid character" error appears right after "done decrypting data".

This happens on a Vista machine as well as on an Ubuntu 7.10 machine.

Comment 6

[dominique.gonzalez]

It should not be possible that it could have relation with it (but when all the possible solutions have been investigated without result the answer must lie with the impossible --Sherlock Holmes--) : I am one of those who were not able to get a verification email (I got it after 3 days).

maybe it can help? maybe not?

Comment 7

[Stefan Max]

I got my verification email the very instant I registered. I doubt any connection to this bug...

Comment 8

[Dan Mills [:thunder]]

Attachment: Don't decrypt cleartext

Bug found.  Attached one-liner patch should fix the problem.
I'll make another release soon.

Comment 9

[Dan Mills [:thunder]]

I just released 0.1.13 with this fix.  Go to Tools -> Add-ons -> Right-click on Weave -> Find update, and restart Firefox.  It should sync correctly now.

Reopen the bug if not.

Comment 10

[Stefan Max]

Works flawlessly for me now. Thanks Dan!

Comment 11

[Dan Mills [:thunder]]

You're welcome! :-)

Comment 12

[dominique.gonzalez]

It seems to work fine for me.
THANKS !!!

Comment 13

[Lucia Clemens]

What is weave?

Comment 14

[Daniel Holbert [:dholbert]]

Weave was the old codename for what is now called "Firefox Sync".

(This bug is long-closed; please don't post questions (or followup issues) here.  If you're experiencing issues with Weave aka Sync, file a new bug for them.)
