+1 here's the [complete log on Travis](https://travis-ci.org/cmey/WaveSim.jl/jobs/380223824)

BTW, GR works well by itself: ``` x = randn(100000) y = randn(100000) hexbin(x, y, nbins=30) ```

I deleted my `~/.julia`, tried with julia 1.5.3, from a clean julia env added only Gtk and GR, and ran gtk_ex.jl. Getting the same exact issue!

I thought maybe my `PATH` or `LD_LIBRARY_PATH` env vars would be causing an issue. I cleaned them down to `export PATH=/usr/bin:/bin:/usr/sbin` and `export LD_LIBRARY_PATH=`, then retried the above again. Still...

Also tried unplugging my external monitors. Same.

Both GR and Gtk tests (`pkg> test Gtk GR`) all pass. There is only a warning produced during Gtk tests: ``` (:3896): Gtk-WARNING **: 15:58:40.970: Could not load a pixbuf...

The latest release of Gtk did not help this issue. `[4c0ca9eb] ↑ Gtk v1.1.6 ⇒ v1.1.7`
