Comment 2 for bug 1259721

Upon further investigation, the problem seems to be that the test apps that are launched by that test leak their stdout descriptor.

What's interesting is if I run:

python -c "from gi.repository import Gio; Gio.DesktopAppInfo.new('gcalctool.desktop').launch_uris([], None)" | tee /tmp/foo

tee will exit as soon as I click the close button on the window. The test code closes the window by sending the NET_WM_CLOSE EWMH signal, which, AFAICT, should be the same thing.
