keyboard shortcuts in context menus are not displayed correctly(?) [pga3-1.8.0]

Hi friends,

on debian latest pakcages we've provider, if I right click to get a
context menu, keyboard shortcuts are displayed with _K instead of the
underlined K. Is it a known issue? Can someone reproduce on another
distro / wx? Please not that everything is fine elsewhere in the app
(File menu for example). A screenshot can be found here:
