The "mgaapplet-upgrade-helper" program crashed. Drakbug-15.54.1 caught it.

Waiting for the upgrade from magina 2 to magina 3 to finish during an on-line upgrade.
The system was a clone of a fully up to date magina 2 system.  This happened overnight
while the machine ran.

Previously another clone of the working machine failed to upgrade using the DvD.  That error
said something about getting stuck in a "Forever loop" checking dependencies. 

Following either upgrade attempt, the machine is left broken (half upgraded).  This clone is dead.  (the original drive still runs mageia 2)
