Ok, I have done a bit more playing, and it seems the problem occurs  
when I press backup on my remote, and no longer when I press esc on  
the keyboard (it used to have the problem with them both). I must  
have been using a combination of keyboard and remote when testing  
earlier (I had a delay between each test due to recompiling)

On checking my lircrc file I find that I had 2 remotes set up, one  
with a key called back and one with a key called BACK. One of the had  
the remote named the other did not. It turns out that its not case  
sensitive, and so when pressing BACK on the named remote (the one I  
now use) it was sending a double esc very quickly.

So it seems that a double esc event posted by lirc does cause a  
problem, but you are not able to press esc twice fast enough on a  
keyboard to cause the problem anymore.

I now have a backtrace file for the problem with the remote (but its  
to big for the limit on the list, I'll create that new ticket now)
