You can either save the PDF before reading (o in Gnus), or just do M-x rename-buffer RET. BTW, how do you get Gnus to open PDFs with DocView in the first place? Attachments can have a filename and a description. So in general I'd assume Gnus would use one of these as buffer names. But maybe they were missing for that attachment you are talking about? (I guess not every mail client does them properly.) Do you have a sample mail which you can forward to this bug report for testing? Bye, Tassilo
