I am working on the translation of the ui and the rtl (bidi) issues
so i use the latest master (27-10-2011)
after last "git pull" i noticed that the question back dialog is empty

i used xdebug to trace it down to:
/question/engine/bank.php (line 202)

$config = self::get_config();

$config = null (funny)
and the:

207: self::qtype_enabled($name)

is always false.

so, no questions in the dialog.

maybe it is a work in progress?
maybe my git pull messed my local code?
maybe it is a bug?
