[Simpletest-support] web form issue

[Tim <da...@fa...>]

Hi,
   So I have been having trouble getting a login working using the the 
browser module, this is only happening on one particular server which is 
RHEL6 w/ php 5.3.13.

Basically the login fails, with the remote server rejecting the request. 
On closer inspection, the post parameters appear to be truncated. i.e 
there is a  validation key that should be

"/wEWBgKg39dCAtHo2bAJAoCO7/gFAraE6F8CoejZkAICz5yEggoKjWoDPyV4u4qbEbtGzIJvWG8IkA=="


but simpletest appears to be sending the following in the post instead


""/wEWBgKg39dCAtHo2bAJAoCO7/gFAraE6F8CoejZkAICz5yEggoKjWoDPyV4u4qbEbtGzIJvWG8IkA"



Any thoughts on what is causing this?

Thanks
   Tim
