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.
