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

I clicked "Save as..." on an attachment, the Save dialog opened and while I was typing the name of the file (after having navigated to the target folder), KMail crashed.

This may be related to background filtering (new incoming mail), or that I had to cancel "Downloading message...", because KMail has been in a loop to download and re-upload this bigger mail (the one with the attachment) again and again, creating a new copy every time (Bug 125084).
