pinentry and gnome shell's top bar cause freeze

Originally created by @segfault on #11038 (Redmine)

While pinentry is running, attempting to start a program (e.g. keepassx) via gnome shell’s top bar causes all windows to freeze. This includes the pinentry window, which makes it impossible to click the close button. The pinentry still grabs the keyboard, so the only way to fix this from within the gnome session seems to be to enter the correct password or entering wrong passwords three times, which causes the pinentry window to close.
