That doesn't make sense to me. What exactly do you mean by "breaks"?
Obviously it doesn't break in the usual sense, so either the iteration is
failing, or the problem is actually somewhere else. I notice that the unsafe
method of QPtrList iteration is used, which makes me suspect that some
nested iteration over 'modules' is happening. Does replacing all the uses of
first()/next() with a QPtrListIterator help?
