This problem also occurs if the data folder is changed to a local
directory and that directory name contains a "space".

The "real" problem is QtGui.QFileDialog.getExistingDirectory(.....

On XP, when a directory is selected, the dialog returns
[drive]:/[directory/directory....] instead of
[drive]:\[directory\directory...]

On Win 7, the path name is returned correctly.

This normally does not cause a problem in OpenLP, until this path is
passed to the powerpoint dll.  For  ome reason, when it sees the "/",
all spaces in the string are changed to &20 (substitution for a space)
which then causes the problem.

I changed the "/"'s to "\" in the registry for the data path name, and
the error went away.
