It looks to me like its trying to draw on a window which doesn't actually yet exist at the Gtk level - this probably means that Show() hasn't yet been called (or at least that it hasn't yet resulted in the window actually being shown). The quick fix is to disable such checks (they are off by default in wx 2.8, so this probably isn't actually a new issue) - details are here: http://anonscm.debian.org/cgit/collab-maint/wx-migration-tools.git/tree/README#n30 If you want to address the reported issue, then I think gating this drawing code on IsShown() returning true for the window should work.
