coercing to Unicode: need string or buffer, tuple found

Ah I see between version 4500 and 4514 in SVN that you introduced the usage of the string_args unicode to string keys. I believe that might be giving me the problem. I don't know if it makes a difference or not but I'm on Python 2.4 on RHEL5.

As you can see in the diff I only moved the position of kwargs = string_keys(kwargs). In [4520] I have updated that parsing to strict=True, this will only affect you if you had '=' signs in you url. I cannot replicate your error, but I added debug code to the sting_keys(kwargs) call. If the problem still persist, please paste the error output so that I have more information to go on.

From the ticket description you have Error: Macro Freemind(wiki://WikiPageName/filename.mm) failed am I correct in assuming that you have a wiki-page named WikiPageName? and you actually attached a file named filename.mm to that page ?

Thanks for the help so far. I do have the wiki page and the mind map names as above. Here is my debug log output after using your latest version of the macro.
