Comment (by SimonKing):

 Nils, I have absolutely no idea how you made messages show up in my screen
 session on bsd.math, and I also have no idea how to answer.

 What I did now: I edited the test file, so that it ends with
 {{{
 #!python
     except BaseException, msg:
         print "an exception has occured"
         print msg
         #quit_sage(verbose=False)
         import traceback
         traceback.print_exc(file=sys.stdout)
         #sys.exit(255)
     print "we would now quit, but we don't"
     #quit_sage(verbose=False)
     #if runner.failures > 254:
     #    sys.exit(254)
     #sys.exit(runner.failures)
 }}}
 Then, attaching the file and quitting sage works fine, and an exception
 does not occur. No idea what that means, though.
