[Zope] external method with import tarfile

Hi! I am trying to run a external python script. Now I am facing a problem that occurs only when I run the script via Zope. ... import os,tarfile ... tar = tarfile.open(oname,"r:gz") for itar in tar: tar.extract(itar.name,jobdir) gives me: Site Error An error was encountered while publishing this resource. Error Type: IOError Error Value: CRC check failed If I comment the for loop my scripts finish well, but then it does not uncompress the file. Please, any help would very appreciated. Many thanks in advance, Cheers, Alan -- Alan Wilter S. da Silva, D.Sc. - Research Associate Department of Biochemistry, University of Cambridge. 80 Tennis Court Road, Cambridge CB2 1GA, UK.
