The dangling dialog occurs due to insufficient dialog matching capabilities
in the current dialog module. As Ovidiu explained in his last mail, a more
strict matching logic could make sure that the right dialog is chosen,
thereby not depending on long timeouts getting triggered.

However, I still do not see what the benefit of having separate dialogs in
the particular case described is, and also believe that there is at least
another major drawback. Let me outline that in the other thread...
