I find this is normally caused by a couple issues, you didn't mention 
what you're hardware is, but if you're using something with one of the 
newer in-kernel modules (eg. mceusb) you're keypresses are probably 
being decoded both in-kernel and by lirc.

if you:
cat /sys/class/rc/rc0/protocols

you should see something like:
rc-5 nec rc-6 jvc sony mce_kbd [lirc]

If anything other the lirc has the brackets, simply
echo lirc > /sys/class/rc/rc0/protocols
and you should be good,

The other main issue I see is people have more then one remote defined 
in, or included by lircd.conf and the same key combination is defined in 
more then one (with the same value).  If you run 'irw' and you press a 
button on your remote, you should see something like:
000000037ff07bde 00 KEY_RIGHT mceusb
If the last field has two different remote names (on subsequent lines), 
or the second field shows two lines with '00' in a row, you most likely 
have an error in your configuration somewhere.

HTH, Andrew.
