Quick strace (grepped for brevity):
# grep -E '(mkdir|getx|rmdir)' log
mkdir("buffy/SendTo", 0700)             = 0
getxattr("buffy/SendTo", "system.posix_acl_access", 0xbfffc330, 132) = -1 ENODATA (No data available)
getxattr("buffy/SendTo", "system.posix_acl_access", 0xbfff9080, 132) = -1 ENODATA (No data available)
rmdir("buffy/SendTo")

There are lots of stat() and stat64() for the buffy directory and buffy/SendTo in between. 
The /var/lib/samba/profiles partition is reiserfs from kernel 2.6 and mounted with the acl 
option. From the grep result above, it seems the SendTo directory is created, probed and 
then removed?! Why?
