Safari 4 invalid auth token

Getting an odd error in Safari 4:

Here's the auth token that's output to my javascript:

4HB8yAW4gU2xEavWOc+kiMoj4XIyCBUK/t704aOQ+co=

Here's what's listed in the parameters:

"authenticity_token"=>"4HB8yAW4gU2xEavWOc kiMoj4XIyCBUK/t704aOQ co="

notice: the +'s are being replaced by spaces.

This a specific safari issue? I haven't even been able to get FF to
give me +'s in my auth token.

Matt, you might want to also log this bug, if you haven’t already done so, by

clicking the bug button in the upper right of the Safari 4 window.

Yep, I already have. If this is a safari only bug, hopefully we can
get this fixed in the nightly soon...
