Mmh, I can't reproduce the crash by myself. I can only messup the assocs.
But try to insert some debug statments in
associationwidget::updateRegionLineCount where it crashes there. I think it
won't crash at this line.

In the function updateRegionLineCount we find e.g. lines like:

ch = static_cast<int>(( wh * index / totalCount));

I think if totalCount is 0, the crash would occur.
