nautilus-clamscan can't scan files larger than 2GB

[Pedro Dias]

When several files are selected for a scan in nautilus, an one of them is larger than 2GB, nautilus-clamscan never finishes the scan and no error is displayed. Only the files processed so far are displayed in the details section.

OS: Ubuntu 10.04.1 LTS

Package versions: linux-generic-pae (2.6.32.25.27), nautilus (1:2.30.1-0ubuntu1.1), nautilus-clamscan (0.2.2-2ubuntu1), clamav (0.96.3+dfsg-2ubuntu1.0.10.04.1)

It is probably a good idea to attach the complete python script, in case the patch is wrong.

Just to make it clear, the patch only handles the exception raised when py_clamav.scanfile() scans a file larger than 2GB, allowing nautilus-clamscan to complete by scanning all the files. It doesn't solve the problem with clamav not being able to scan files larger than 2GB. By executing 'clamscan -r' on a directory with files larger than 2GB, it avoids scanning these files. By forcing it with 'clamscan <filename>' it blows up with the error:

WARNING: Can't access file xpto.avi
