Thanks for the reproducible report. I don't think this is normal indeed.
I've made a pull request to fix this here:
https://github.com/JuliaLang/julia/pull/8323
But the code you're calling above is equivalent to find(A), which works
fine, and which is specialized for sparse matrices, meaning it's more
efficient.
