[PD] test5, problem with special characters in patches' filenames

[Dario Sanfilippo]

There seems to be a problem with special characters in filenames, namely
round parentheses (I haven't tested the other ones).

I'm on OSX 10.11.6 and, if PD is closed and I open the attached patch, I
get the following error (below) on the PD window. If PD is open and I drag
the on to the PD icon I get the same kind of error as an Application Error
pop-up window.

This patch will still work after I get the errors but I have a large patch
containing parentheses in the filename and things are different: If PD is
closed and I right-click on the file and ask to open with PD, I get the
error in the PD window but the patch works; if PD is open and I drag the
file on it, I get the pop-up error and no operations can be performed on
the patch. I.e., I can't change any of the GUI with the mouse or even close
the patch pressing cmd + w. I can still close it by clicking on the "close"
button in the window.

Cheers,
Dario
