[Qt-interest] QStringList copy constructor doing something funny?

[Jaco Naude]

Well, there is not any other code. I break the debugger on the line where it
breaks and I can see all three items in the QStringList. When I click "Step
Over" it crashes, and if I "Step Into" it also crashes without any
additional info.
