Bug#859324: glade: eats unrelated key-repeat events

[Matthias Urlichs]

Package: glade
Version: 3.20.0-2
Severity: normal

Apparently, when a nontrivial Glade window is in the foreground, somehow
key repeat events get clobbered.

$ xxxxxxxxxxxxx … (key repeats normally)
$ glade FOO.glade
xx (key repeats irregularly, every couple of seconds)
< minimize Glade window or switch screens)
xxxxxxxxxxxx … (normal again)

The problem also disappears when Glade is interrupted or when the content
it shows is empty. Thus this seems to be a problem with at least one of its widgets.

Exhibited by papermate's frontend/mainwindow/mainwindow.glade file.
I have attached a hopefully-minimal file that exhibits the bug.
