fillItems() method - segmentation fault solved

I had an FXRuby app that was randomly segfaulting at the following code
line:

listbox.clearItems()
listbox.fillItems(some_string_array)

It would segfault when executing .fillItems, but the segfault was
unpredictable and seemingly without reason. After weeks of struggle, I
discovered that if instead I do:

listbox.clearItems()
some_string_array.each { |item| listbox.appendItem(item) }

the code works fine and never segfaults. So, the issue seems to be
somewhere in the .fillItems method.

Anyway, I thought I’d post this in case others experience problems with
the .fillItems method.
