PATCH: unix shellfolder crash

[Marcus Meissner]

Hi,

Winamp 5.1 crashes when adding Directories of MP3s to the
playlist in the unixfs shellfolder handling.

This workaround cures the problem and the unixfs handling
is still there.

Ciao, Marcus

Changelog:
	Michael Jung <mjung at iss.tu-darmstadt.de>
	Fixed crash in unixfs shellfolder handling with winamp.
