Seahorse opens a dlgQuestion for Deleting a password entry ldtp isn't able to interact with it

[Dave Morley]

Using this code to delete a usc password entry stalls at the dlgQuestion;

  ldtp.launchapp('seahorse')
  ldtp.waittillguiexist('frmPasswordsandKeys')
  ldtp.expandtablecell('frmPasswordsandKeys', 'ttbl0', 0, 1)
  ldtp.waittillguiexist('dlgPasswords:login')
  ldtp.mouseleftclick('dlgPasswords:login', 'btnClose')
  ldtp.waittillguinotexist('dlgPasswords;login')
  if ldtp.doesrowexist('frmPasswordsandKeys', 'ttbl0', 'Ubuntu Software Center Store') == 1:
   ldtp.selectrow('frmPasswordsandKeys', 'ttbl0', 'Ubuntu Software Center Store')
   ldtp.selectmenuitem('frmPasswordsandKeys', 'mnuDelete')
   assert ldtp.waittillguiexist('dlgQuestion') ***
   ldtp.click('dlgQuestion', 'btnCancel')
  elif ldtp.doesrowexist('frmPasswordsandKeys', 'ttbl0', 'Ubuntu Software Center') == 1:
   ldtp.selectrow('frmPasswordsandKeys', 'ttbl0', 'Ubuntu Software Center')
   ldtp.selectmenuitem('frmPasswordsandKeys', 'mnuDelete')
   assert ldtp.waittillguiexist('dlgQuestion')
   ldtp.click('dlgQuestion', 'btnCancel') ***
  ldtp.selectmenuitem('frmPasswordsandKeys', 'mnuQuit')

the lines with *** at the end are the ones not seen. Could be an issue in atspi however accerciser seems to see the dlg window.
