Rust, SAFE Network, Crust and a problem for Fedora 22 x86_64 XFCE (ie not other spins)

[Philip Rhoades]

People,

I have been getting heavily involved with this project:

   maidsafe.net / maidsafe.org

and I have a problem (real hardware and VMs) that occurs with building 
the software which doesn't happen for other Fedora 22 spins or if I 
build the software in a Docker image.  To reproduce the problem do this:

As root:

   curl -sSf https://static.rust-lang.org/rustup.sh | sh -s -- 
--channel=nightly
   dnf install libsodium-devel

As any user:

   git clone https://github.com/maidsafe/crust
   cd crust
   cargo build
   RUST_TEST_THREADS=1 cargo test

You should see something like this:


Running target/debug/crust-991e24481699f6b2

test result: ok. 22 passed; 0 failed; 1 ignored; 0 measured


Instead for an XFCE environment I see this:


Running target/debug/crust-935be27542bb08fc

running 23 tests
test beacon::test::test_avoid_beacon ... thread 'test_avoid_beacon 
seek_peers 2' panicked at 'index out of bounds: the len is 0 but the 
index is 0', ../src/libcollections/vec.rs:1047


- which also hangs indefinitely . . I have NO idea why a desktop 
environment should cause this sort of problem - anyone got any ideas?

Thanks,

Phil.
