 in rts/System/Config/ConfigLocater.cpp we have:

  37 #ifndef _WIN32
  38 const string base = ".springrc";
  39 const string home = getenv("HOME");
  40
  41 const string defCfg = home + "/" + base;

By browsing the web, i found out that the HOME env var is usually only set for real persons user accounts.
I assume this is run by a special buildbot user, that does not have HOME set (can be "simulated" with "unset -v HOME").

This problem is handled by this stackoverflow question, and the accepted answer plus the comment to it seem like exactly what we need.
http://stackoverflow.com/questions/2910377/get-home-directory-in-linux-c

my suggestion:
use HOME if it is set, otherwise use:
   struct passwd* pw = getpwuid(getuid());
   const char* homedir = pw->pw_dir;
and optionally set the HOME variable to that value, so we can use it in other places in the engine, should need arise.

edit: doing it
