bug in du: truncates filenames

[Pierre Abbat]

I'm running du on snapshots to see how much space is taken by work directories 
(which will stick around for over another month; the downloaded tarballs will 
disappear in just a few days). I got this error:

# du -s /var/hammer/usr/snap-20111?11*/pkgsrc/
du: /var/hammer/usr/snap-20111111-0501/pkgsrc/x11/xterm/work/xterm-259/xtermcfg.h: 
No such file or directory
du: /var/hammer/usr/snap-20111111-0501/pkgsrc/x11/xterm/work/xterm-259/Makefile: 
No such file or directory

I checked the directory; the files are actually Makefile.in and xtermcfg.hin . 
It's not simply truncating the filename to a fixed length, since there's a 
file named xterm.log.html , which is longer. Any idea what's going on?
