Trying to load Gtk bindings fail, then gst crash:

st> PackageLoader fileInPackage: 'BloxGTK'!
"Global garbage collection... done"
Loading package GTK
Object: <unnamed Behavior> new "<0x2ac35579b9d0>" error: Invalid index 15: index out of range
SystemExceptions.IndexOutOfRange(Smalltalk.Exception)>>signal
SystemExceptions.IndexOutOfRange class>>signalOn:withIndex:
<no name>(Smalltalk.Object)>>instVarAt:
<no name>(Smalltalk.Object)>>mutate:startAt:newClass:

(what's described below occurs on a Debian GNU/Linux amd64 box)

attaching gdb on it seems to show it loops allocating memory. If I Ctrl-C, it stops.

But then trying to launch it again fails with:

gst: Aborted
(ip 4)[] in ProcessorScheduler>>#initialize
(ip 22)Array(SequenceableCollection)>>#do:
(ip 6)[] in ProcessorScheduler>>#initialize

How to duplicate:
