Mudlet crashes when too many lines are deleted to start of buffer

[Vadim Peretokin]

Open a profile, create a trigger with the following code and make it run to crash Mudlet:

local startline = getLineNumber()
for i = 1, 5000 do
  deleteLine()
  moveCursor(0, startline-i)
end

Crashed on the assertion:

inline T &QList<T>::operator[](int i)
{ Q_ASSERT_X(i >= 0 && i < p.size(), "QList<T>::operator[]", "index out of range");
  detach(); return reinterpret_cast<Node *>(p.at(i))->t(); }

Happens everytime.
