727648 - DAV (Lightning + Google Calendar) broken in recent nightly builds

Status: RESOLVED DUPLICATE of bug 727943

(Thunderbird :: General, defect)

Description

[Matthew Turnbull [Bluefang]]

DAV (Lightning + Google Calendar) seems to be broken in recent nightly builds. The calendar fails to load, and I see the following errors in the console:

--
Warning: There has been an error reading data for calendar: Personal.  However, this error is believed to be minor, so the program will attempt to continue. Error code: DAV_NOT_DAV. Description: The resource at https://www.google.com/calendar/dav/****/events is either not a DAV collection or not available
--
Warning: There has been an error reading data for calendar: Personal.  However, this error is believed to be minor, so the program will attempt to continue. Error code: READ_FAILED. Description: 
--

Switching to older Lightning builds did not help. Switching to older Thunderbird builds did. Regression range:

Good: http://ftp.mozilla.org/pub/mozilla.org/thunderbird/nightly/2012/02/2012-02-08-03-00-40-comm-central/
http://hg.mozilla.org/mozilla-central/rev/4b9608fd670c

Bad: http://ftp.mozilla.org/pub/mozilla.org/thunderbird/nightly/2012/02/2012-02-09-09-02-29-comm-central/

I grabbed those links from about:buildconfig. Seems odd that they're pointing to mozilla-central, but whatever... Also not sure if this belongs to Thunderbird or Core/Toolkit.

You should have filed this bug for Lightning. Would had save me some time that I spend to find the same regression range Bug 727943 ...
Workaround: Set advanced preference "network.http.spdy.enabled" to "false".
