I also ran into problems with ktruss recently, on NetBSD 5.0.1/i386.
For example, an open() system call which ktrace + kdump reported like
15159 1 testprog CALL open(0xbb80208c,0,0xbfbfe7e8)
15159 1 testprog NAMI "/dev/rwd0a"
15159 1 testprog RET open 3
ktruss reported like this:
11230 1 testprog open("/etc/malloc.conf", 0, 0xbfbfe7e8) = 3
Note how the argument "/dev/rwd0a" has turned into "/etc/malloc.conf".
