Version-Release number of selected component (if applicable):

kernel-2.6.15-1.1830_FC4

How reproducible:

It happens every time I run mplayer on an sshfs fuse mount file.

Steps to Reproduce:
1.sshfs mount a remote directory containing a movie
2.Use mplayer to play the file (no problem with playback)
3.Note syslog message
  
Actual results:

Message in /var/log/messages

Expected results:

No error

Additional info:

Simply copies of some data from the mounted remote directory don't seem to
trigger the message.  I've only been able to trigger it with mplayer.
