Closing the first figure disables the following figures

Symptoms look related to https://github.com/JuliaPy/PyPlot.jl/issues/179, but I'm on linux; a friend has the exact same bug. Backend is TkAgg. Possibly related: only the first figure has a task bar icon.

When I do figure(); plot(1); figure(); plot(1) and I close the first figure (through the GUI or close(1)), the second figure becomes unresponsive. I am able to close() it and everything works fine again, though. Works fine through python.
