Long file name attachments in Yahoo mail 2. Download 3. Actual Results: file name truncated Expected Results: saved full filename to hard drive may be specific to Yahoo Mail, but has been seen by at least two separate users on multiple occasions

All file names have spaces, (some of) the underscores are only for display by yahoo (see bug 252309 comment 0 step 4). The filename is truncated at the first real space. It is the issue from bug 221028. To evangelize we have already a bug for yahoo, so marking as dupe. *** This bug has been marked as a duplicate of 252309 ***
