I have traced the calls down till admin_get_fields function. I found
that it returns incorrect field type in "Type" key, but "type" key (from
lover case letter) contains correct value.
This function calls MetaType function for each field in a table passing
value from "type" array member and table name.
MetaType function, in case ADODB is used, performs SQL query "SELECT *
FROM <table> LIMIT 1" and calls MetaType function from returned object.
BUT ONLY if table name exists in cache_fieldType class variable.
Existence is checked by in_array($table, $this->cache_fieldType).

BUT!!! $this->cache_fieldType is not an array, it's a dictionary! So,
in_array will always return false. array_key_exists must be used instead!

I have made a patch (http://forge.typo3.org/issues/32427). It works OK
for me.
