Package: src:jekyll
Version: 3.1.6+dfsg-3
Severity: serious

Dear maintainer:

I tried to build this package in stretch with "dpkg-buildpackage -A"
(which is what the "Arch: all" autobuilder would do to build it)
but it failed:

--------------------------------------------------------------------------------

The relevant part of the build log is included above.

The failure happens randomly. Sometimes it fails, sometimes it does not.

I'm attaching several build logs, made on different autobuilders.

If (after trying a lot of times) you could not reproduce this using
sbuild on a single CPU virtual machine (as I did), please do not
downgrade or mark as unreproducible, I would then consider giving you
access to a virtual machine on which I can reproduce it so that you
can as well. (In such case, please contact me off-list for details).

Thanks.
