MySQL error 1054 when accessing any lead

[southwestcrm]

Version OS4.5.1d
MySQL 4.1.21

When clicking on a name in the leads list in listview, the lead does not open and I get the following error message.

Error retrieving Lead list: Query Failed:SELECT leads.*, users.user_name assigned_user_name FROM leads LEFT JOIN users ON leads.assigned_user_id=users.id where leads.deleted=0 ORDER BY name ASC LIMIT 33,1::MySQL error 1054: Unknown column 'name' in 'order clause'

Any ideas anyone why this is happening?
It happens on every lead.
Some leads were imported from CSV other entered from a webtolead capture form.
any help appreciated.

Many thanks. That fixed it.

Do you know if this is an issue with Sugar? Will the next upgrade overwrite the fix provided and reintroduce the bug?
