I don't know where that spot might be, unless it's in the debugging log. 
But I noticed something when looking at the log. It BURNS track 1. When 
it goes to verify, though, the progress-indicating part of K3B reports 
that it's "Verifying track 0."

On a hunch, I tried another burn with K3B set to NOT eject the CD after 
burning. (Under Settings > Advanced Settings > Miscellaneous.) It 
verified with no problem. So perhaps it's some interaction between HAL 
and K3B when the disc is reinserted?
