Bug: I insert a row in my (big) spread sheet, and KSpreadCell::calc runs into
an infinite loop, calling itself when doing calc() in its dependencies
(cell->calc(), where cell==this).

BTW I just tried inserting a row on a very simple spread sheet with
F5:345 and F6:=F5, (and inserting a row between the two). Although the infinite 
loop doesn't happen there, I get tons of those:
kspread: WARNING: Error: Calling KSpreadCell::row() for default cell
kspread: WARNING: Error: Calling KSpreadCell::column() for default cell
kspread: KSpreadCluster::lookup: invalid column or row value (col: -1  | row: 0)
kspread: KSpreadColumnCluster::lookup: invalid column value (col: -1)
kspread: KSpreadCluster::lookup: invalid column or row value (col: 0  | row: -1)
kspread: KSpreadRowCluster::lookup: invalid row value (row: -1)

Actually the strange thing is that in my big spread sheet, there's *no* formula
below the row being inserted (only tons of them above), so I don't see how inserting
a row could have any effect on the dependencies... it shouldn't.

PS: I tried adding a (if cell != this) in calc, but then the infinite loop only moves to

Hmm.
