> Is this something that re-appeared recently?
no, it's been around for some time

> Is this something that only appeared after a Qt upgrade?
no, happens for me with Qt4.7.4

> Can you add some debug output above the assert with information relevant to the assert?
today krop some experiments and showed this

<krop> (gdb) p m_includeAllSelected
[10:17] <krop> $1 = true
[10:17] <krop> (gdb) p sourceTopLeft
[10:17] <krop> $2 = {r = 7, c = 0, p = 0x104c540, m = 0x826f50}
[10:17] <krop> (gdb) p sourceBottomLeft 
[10:17] <krop> $3 = {r = 4, c = 0, p = 0x1058fb0, m = 0x826f50}


I noticed that the rows in the bottom is less than the row of the top.
does that matter?

If I do this on line 1645

if(sourceBottomLeft.row() <= sourceTopLeft.row())
  return;

then I no longer get into the assert.

does any of this info help?
