I suggest turning it around; let the application query some global object 
via dbus and get a list of conflicting keypresses only (low memory).
You should do this (shortly) after the app shown its window to avoid 
network latency slowing down the startup, but my guess would be that it 
would be faster than loading / parsing files from disk.
