Self-referential playlist kills Winamp 5.08d

[ettlz]

Winamp 5.08d
Windows XP SP2
HP zx5030EA notebook (P4 2.8 GHz, 512 Mb RAM)

Create a M3U playlist file (e.g., playlist.m3u) and put that playlist's own filename in as an entry. Attempting to load the playlist [by drag and drop onto the playlist window] results in Winamp closing instantly.

There is no "application error" box or entry in the system event log.
