           Summary: Blank attachment at opening, when switching mail using
                    load on demand imap
           Product: kmail
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs kde org
        ReportedBy: dump tzib net


Version:            (using KDE KDE 3.5.5)
Installed from:    Ubuntu Packages
OS:                Linux

How to reproduce:
Get an imap account with "load on demand" activated.
Send yourself or get email with a big attached, that will at least take a few seconds for you to download.
For test purpose use a openoffice or text file so that you can see the result clearly (fill that file with whatever data of course).


quit kmail so that the attachement is not in a temp file, start it, and open the big attachement.
While it is downloading (see the progress bar), switch to any other mail

wait until the attachement opens in the background. when it finally open, you will get a blank file without contents.

I could reproduce this on different distributions also running kde 3.5.5.

Of course, disabling "load on demand" is a work around for this.

Thanks :)
