PyPlot and ImageView

[Lightjohn]

Hello, I don't know if it's a known bug, but I could reproduce it on three linux mint 17.2 and julia 0.3.11.

using PyPlot
matshow(rand(10, 10))  //Everything is good
using ImageView
matshow(rand(10, 10))  //Will crash with following message:

The crash error message is (it kills julia):

Fatal Python error: PyEval_RestoreThread: NULL tstate

And just the fact to include ImageView is enough !

Do you have an idea ?

It's probably a Tk-related bug. I'm partway through a rewrite of ImageView based on Gtk, but it's not ready yet.

[giordano]

I've also been hit by this bug (but I can live with it). Any progress on the work with Gtk?

[timholy]

I'm completely overwhelmed with JuliaImages/Images.jl#542, which is a predecessor to the ImageView rewrite. Significant progress announced yesterday: JuliaImages/ImageFiltering.jl#5.

[giordano]

That's fine. As I said, I can live with this problem, no rush ;-)

Does not crash for me with current ImageView.
