Soundfont oddness in nightly builds

On Windows 8.1, if you try to run a nightly and the copy of MuseScoreDevelopment.ini in your AppData\Roaming\MuseScore directory lists a nonexistent directory in sfPath (say, because you have deleted an earlier nightly), the directory gets created.

For example, I recently discovered that even though I had deleted MuseScoreNightly-2015-05-08-1618-a4f311c, when I ran a different nightly build (MuseScoreNightly-2015-05-09-1209-6356462), an empty directory path matching the now obsolete entry in sfPath ("C:/Users/Grant/Downloads/MuseScoreNightly-2015-05-08-1618-a4f311c/MuseScoreNightly/sound") was created. It seems wrong to me that referring to a nonexistent directory should cause it to exist.
