strace is your friend:
# strace -e open cat ""
open("/etc/ld.so.cache", O_RDONLY) = 3
open("/lib/libc.so.5", O_RDONLY) = 3
open("/usr/share/locale/locale.alias", O_RDONLY) = 3
open("/usr/share/i18n/locale.alias", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/share/locale/de_DE/LC_CTYPE", O_RDONLY) = 3
===> open("", O_RDONLY) = -1 ENOENT (No such file or directory)
cat: : No such file or directory
