Qrexec getting spammed by split-gpg2

[Yangdong]

Hi qubes-users,

When using split-gpg2 (and maybe split-gpg, I'm not particularly sure),
if something unexpected happens during the process (say the gpg client
which initiated the exchange crashes or I click "Cancel" in the
dom0 dialogue box), something happens and dom0 gets spammed with a bunch
of the qrexec confirmation dialogue boxes and it becomes difficult to
clean.

Does anyone know of a way to prevent this?

Best regards,
