Vim crashes when saving files

[Ernaldis]

rust.vim version:

I installed the plugin with Vundle. The current commit of the repository it cloned is:
commit 4aa69b84c8a58fcec6b6dad6fe244b916b1cf830 (HEAD -> master, origin/master, origin/HEAD)

Steps to reproduce:

In terminal:
vim hello.rs
In vim:
:w

Expected vs. actual behavior:

• Expected:
  save the file
• Actual:
  editor exits with the following error message:

[4]+  Stopped                 vim hellp.rs
exit
There are stopped jobs.

Running ls -a reveals that there is still a file called .hellp.rs.swp

Paste debugging info from the Rust Vim plugin via one of the following

commands: :RustInfo, :RustInfoToClipboard, or :RustInfoToFile <filename>.

Running any of the commands listed causes a crash similar to the one caused by saving the file.
