-- Information about the crash:
KMail crashed when saving a pdf attachment. The crash happens after the save file dialog has been opened and the moment the button to Save is pressed. (The file is not saved.) This has happened before a few times now. But it also happens that saving does work.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
