Description

From a brief look at the Systembar destructor I'd say the iterator is not positioned correctly for a call to value() (and without value() calling abort() this probably would have been an endless loop since the iterator is never incremented):
while (i.hasNext()) {
if (i.value()) {
delete i.value();
}
I added a line:
while (i.hasNext()) {
i.next();
if (i.value()) {
delete i.value();
}
And the crash is gone...
systembar was in playground, doesn't exist anymore Closing bug.
