I've found an issue with the latest Beaker under flup-0.5 FastCGI.
Beaker was sending bad headers (a None value) during HTTP redirects.
This is probably the issue you're seeing, although the exception
traceback I saw was different:
Module pylons.error:335 in detect_start_response
return start_response(status, headers, exc_info)
Module paste.errordocument:172 in change_response
return start_response(status, headers, exc_info)
Module flup.server.fcgi_base:1102 in start_response
assert type(val) is str, 'Header values must be strings'
exceptions.AssertionError: Header values must be strings
Please give the latest Beaker a shot; I believe these are the same
issues unearthing themselves differently. To install the latest
Beaker via easy_install, do:
easy_install -U http://beaker.groovie.org/svn/trunk/Beaker
FYI: I did not see this error under the normal Paste http server. It
must do less assertion checks than flup does; I'll see if I can sync
those up or at least log a Paste ticket about it.
