Zend_Gdata_GdataOnlineTest::testPostRetrieveEntryAndDelete is failing on my machine:
<pre class="highlight">testPostRetrieveEntryAndDelete(Zend_Gdata_GdataOnlineTest) Zend_Gdata_App_HttpException: Unable to read response, or response is empty library/Zend/Gdata/App.php:483 library/Zend/Gdata.php:201 library/Zend/Gdata/App.php:610 library/Zend/Gdata/App.php:541 library/Zend/Gdata/App.php:159 library/Zend/Gdata.php:169
I'm tracked the breakage to r11768. I'm currently attempting to isolate the cause.

Attaching packet capture.
This part is interesting:
<pre class="highlight">No. Time Source Destination Protocol Info 17 0.453789 172.19.246.207 126.96.36.199 TCP [TCP segment of a reassembled PDU] 18 0.535081 188.8.131.52 172.19.246.207 TCP http > 49705 [ACK] Seq=1769 Ack=681 Win=7040 Len=0 TSV=3186164309 TSER=299462861 19 0.548198 184.108.40.206 172.19.246.207 TCP http > 49706 [ACK] Seq=1 Ack=443 Win=6784 Len=0 TSV=3185779522 TSER=299462861 20 20.454967 172.19.246.207 220.127.116.11 TCP 49706 > http [FIN, ACK] Seq=443 Ack=1 Win=524280 Len=0 TSV=299463061 TSER=3185779522
It seems that my client begins a request, the server ACKs, and then nothing happens for 20 seconds until my client sends a FIN.
(172.19.246.207 = me, 18.104.22.168 = remote server)

Alright, it seems that there's a problem has to do with the Content-Length HTTP header.
If, in Zend_Http_Client, I change:
const CONTENT_LENGTH = 'Content-Length';
const CONTENT_LENGTH = 'content-length';
then the test passes. (This would be a partial revert of r11768.)

Moving to component Zend_Http_Client.
The problem was that Zend_Http_Client's internal header's array is indexed by lowercase header names, regardless of the actual header. The changes in r11768 were looking up headers using a non-normalized name, which would always fail.
Fixed in r11857.

Fixed also for the 1.6.2 (r11880).
