I agree. I did the memset and reshuffled some other initializations and 
still get the crash, here:

(gdb) up
#1  0x080acc39 in -[FSVarioMatrix resetCursorRects] (self=0xb7dd098c,
    _cmd=0x863bb04) at FSVarioMatrix.m:418
418                             cr = [datasrc matrix:self 
columnRangeForCell:cell];
(gdb) p cell
$1 = {row = 135341688, column = 0, dx = <optimized out>, dy = <optimized 
out>}

I suppose the rownumber is quite bogus here, but I can't see how it 
happens to. the type seem to be of type "int" and consisntent, 
FSMakeCell is an inline function...
