[OT] Python Q: expected string, tuple found

[jburtram]

The error says:
TypeError: sequence item 0:
which is 'header'
I would try to print out that value and see what's in there.  It may give you a better idea where to start.

Subject: [OT] Python Q: expected string, tuple found 
 
I'm trying to run a python script called crucible.py (from Atlassian, for their Crucible product.)   While I'm waiting for their support, I wanted to ask here for help understanding python.

The script is supposed to setup a code review for a local subversion working copy, but it can't even login to the Crucible server.  Using the --debug flag, here is what I get:

    self.putheader(hdr, value)
  File "/usr/local/lib/python2.7/httplib.py", line 924, in putheader
    str = '%s: %s' % (header, '\r\n\t'.join(values))
TypeError: sequence item 0: expected string, tuple found

So, somewhere a tuple is not being converted to string.  Not sure if it's the headers, or extra payload since the log message is sanitized by the logger.  The script is http://pastebin.com/3zeYm2qC and line 493 is where the problem starts.  Any suggestions?

I think I could do something like 

values = ','.join(str(value_list)[1:-1])

but I'm not sure how, and I'm pretty sure that it's the code in crucible.py that is the problem, not in httplib.py
