[Snowy] "Invalid signature" error when syncing from Mac to Snowy

[Jeremy Malcolm <Jeremy malcolm id au>]

Just installed Snowy on Apache with MySQL, and my Tomboy client is the latest one for Mac OS X.  All seemed well with the installation, but when I try to sync I get "Failed to synchronise" with a blank details section, and this in the server's error log:

[Thu Feb 17 09:37:00 2011] [error] Content-Type: text/html; charset=utf-8
[Thu Feb 17 09:37:00 2011] [error] WWW-Authenticate: OAuth realm="OAuth"
[Thu Feb 17 09:37:00 2011] [error]
[Thu Feb 17 09:37:00 2011] [error] Invalid signature. Expected signature base string: GET&http%3A%2F%2Fsnowy.malcolm.id.au%2Fapi%2F1.0%2F&oauth_consumer_key%3Danyone%26oauth_nonce%3D967034%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1297953207%26oauth_token%3Dwxxxxxxxxxxxxxxx%26oauth_version%3D1.0

I also noticed in the access log entries like this:

118.107.224.16 - - [17/Feb/2011:22:51:34 +0800] "POST /oauth/authenticate/ HTTP/1.1" 302 - "http://snowy.malcolm.id.au/oauth/authenticate/?oauth_token=3eDxxxxxxxxxxxxxxx&oauth_callback=http%3a%2f%2flocalhost%3a8000%2ftomboy-web-sync%2f"; "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-GB; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13"

Strangely there is a reference to localhost:8000 in that line from the access log, though nowhere do I have that host and port combination configured (though it is hard-coded in core/management/commands/check.py).

Do you have any suggestions?  Searching the Web and this list for "Invalid signature" did not help.

Thanks!
