Description
If a user clicks a login link from the front page of the site (as opposed to clicking on a course), and then logs in as a student, an error message is displayed, in the middle of the course listing.
"Fatal Error: Call to a member function get_access_icons() on a non-object in C:\moodle\course\lib.php on line 1575".
Upon further investigate the failure is in course/lib.php:1575
echo $enrol->get_access_icons($course);
$enrol appears to be a non-object because of a failure in the call on line 1574:
$enrol = enrolment_factory::factory($course->enrol);
In this case $course->enrol appears to equal a single space(" "). I have worked around it by changing enrol/enrol.class.php:10 to
if ((!$enrol) | (trim($enrol) == "")) {
But I believe the issue exists within course/lib.php, as $course->enrol should not be a single space (" ").

Thanks!
In theory we are converting back all those " " (spaces) to "" (empty string) in all the dmlib getXXX functions(). Obviously we have forgotten to do the conversion somewhere (as defined by this bug). I'll take a look to it in some hours (trying to find the origin and to fix it there).
Ciao 
Argh. Sorry the correct bug is MDL-8134. (copy/paste is far from my skills) 
Assigning to Eloy our Oracle guru, the problem is most probably cause by the null workaround used for oracle databases - empty string is used to indicate site default enrolment plugin, which is converted to space...
