Strange behavior from libsoup 2.26.1 + iPhoto

["W. Michael Petullo" <mike flyn org>]

I'm seeing some strange behavior from libsoup 2.26.1. I am using  
libsoup to implement an HTTP server that interacts with an iPhoto  
client. I am finding that soup-socket.c:soup_socket_read_until "gives  
up" right before reading the "\r\n" boundary. As a result, soup- 
message-io.c:read_metadata() reads, for example, GET [uri] HTTP/1.1,  
but not the trailing "\r\n" during the first read_until call. The  
next call reads the "\r\n", causing read_metadata to return before  
reading the rest of the header data. Eventually, this causes a "Bad  
Request" state.

I have added print statements throughout the code and also looked at  
what is going on using wireshark. As far as I can tell, the client is  
making a valid request. All of the header data is there, but things  
just don't seem to work right.

I can not figure out what is going on. Libsoup 2.24.2.1 works fine  
with the same code (no other change).

Thanks.
