[bt-devel] Help with keys

This is probably caused by the bahaviour of the Treekeychooser, which inserts 
into  the first (toplevel) chooser an empty entry at the beginning which will 
later be chosen as default.

CDisplayWindow::init calls this code:
  if (key())
    key()->key(keyName);

The key returned by key() was set in the constructor of CLexiconReadWindow, 
which creates a key which type depends on the type of module it gets as 
parameter.
So key() returns normally something not null, otherwise something goes wrong. 
Why do you think it's NULL?

keyName might be sometimes equal to QString::null, but ony when no key was 
chosen at which the module should be opened.
