Exception when loading workspace

Once of my teammates gets the following error when attempting to load a
repository workspace:
!ENTRY com.ibm.team.filesystem.ide.ui 4 -1 2009-02-16 16:56:04.236
!MESSAGE Problems refreshing on external ignore file change
!SUBENTRY 1 com.ibm.team.filesystem.ide.ui 4 0 2009-02-16 16:56:04.236

I'm able to load his workspace without issue on my machine. Any thoughts
as to why he's getting this exception?

Thanks, Brian
