[BUG] libGL error when passing 3d-arrays with two leading dimensions 1

[mfherbst]

Details

Running

using Plots
plot(reshape(rand(3), 1, 1, 3))

gives a Julia crash with

libGL error: MESA-LOADER: failed to open iris (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)
libGL error: failed to load driver: iris
libGL error: MESA-LOADER: failed to open iris (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)
libGL error: failed to load driver: iris
libGL error: MESA-LOADER: failed to open swrast (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)
libGL error: failed to load driver: swrast
X Error of failed request:  GLXBadContext
  Major opcode of failed request:  152 (GLX)
  Minor opcode of failed request:  6 (X_GLXIsDirect)
  Serial number of failed request:  46
  Current serial number in output stream:  45

If I do reshape(..., 1, 3) or reshape(..., 1, 1, 1, 3) than the result is sane (Either an error or a nice plot).
