#ifdef QT_BUG_CRASH_IN_TAKECHILD_WORKAROUND
// These 3 lines are normally not needed. But apparently a bug (in Qt ??) causes Qt to crash when takeChild() is called. If we remove everything from the
// tree widget before updating it, takeChild() is never called, but the all tree is filled again from scratch. This is less efficient obviously, and
// also collapses the tree. Because it is a *temporary* fix, I dont take the effort to save open/collapsed items yet. If we cannot find a proper way to fix
// this, then we'll need to implement the two missing functions to save open/collapsed items.
