concatenation error

[ekressmiller]

We got a user error message that looks like it might be referencing this line of code (or an identical line somewhere):

docassemble-AssemblyLine/docassemble/AssemblyLine/data/questions/al_document.yml

Line 39 in f787e85

log(word('E-mail was sent to') + ' ' + action_argument('email') ,'success')

Excerpt of error (let me know if you need more):

TypeError:
TypeError: can only concatenate str (not "list") to str
In line: log(word('E-mail was sent to') + ' ' + action_argument('email') ,'success')

I wonder if the person might have tried to email to multiple addresses? Have not yet tested that out.
