avastgui problem with the quick scan

When I execute a quick scan with the avastgui all the files are reported in the results popup window as:
[ filename ] [ Error while scanning ] [File was not tested due to configuration details]

Standard and thorough scans are fine. Is there a bug being worked with regards to the quick scan routine?

Did you have any file on the Exclusion list?

No. I was scanning the home directory.
