Hi Guix,

It appears that the attatched derivation to build webkitgtk using the 
following guix

```
Generation 2	Jun 26 2019 20:21:09	(current)
  guix ba91247
    repository URL: https://git.savannah.gnu.org/git/guix.git
    branch: master
    commit: ba912479e8481d69b699ce348b35d5d70f0c9367
```

fails to build in a way that looks like a race. The suspicious lines in 
the attatched log are:

```
Traceback (most recent call last):
  File "/tmp/guix-build-webkitgtk-2.24.2.drv-0/webkitgtk-2.24.2/Source/WebKit/Scripts/generate-message-receiver.py", line 28, in <module>
    import webkit.messages
EOFError: EOF read where object expected
```

I have been able to sucessfully build webkitgtk on multiple hosts by using 
`-c 2`

Best,
Jack

The previously attatched log was generated with -c 12. I am currently 
running a build with -c 1 to verify that the problem occurs there as well.

(I remember it happening with -c 1 in the past, but my memory could be 
faulty).

I've confirmed that webkitgtk also fails to build for me with -c 1. Log 
attatched.

Subject: webkitgtk fixed in later release?
Date: Mon, 23 Sep 2019 16:54:45 -0400 (EDT)

Today I was able to build webkitgkt 2.24.4 with Guix commit 
4343eebfc9f7d44ec9a665f3374d1397301b542e. It looks like it is also 
available on ci.guix.gnu.org:

https://ci.guix.gnu.org/25hz999kgcjh4alm6liwm12jm3blf5zz.narinfo

This is a newer release of webkitgtk than the one that failed (2.24.2). 
Do we think this means that webkitgtk build problem has been fixed, or did 
we just get lucky with this release?

My feeling is that we should close this bug and can open a new one if it 
re-occurs.

Thoughts?
Jack

I agree.  Closed!
