main.mysqldump fails sporadically in buildbot

Description

http://buildbot.askmonty.org/buildbot/builders/kvm-deb-wheezy-amd64/builds/3197/steps/test_4/logs/stdio

The error message 'Error: 2002 Can't connect to local MySQL server through socket '' (111 "Connection refused")' can happen if the socket value is empty. In the test, mysqlimport is run with my.cnf from the vardir, and this config has a socket value in the [client] section. So, can it be that the file gets overridden due to some race condition?

Same log, a different failure with xtradb:
