-- Information about the crash:
Hello
I use Kontact 4.4.2 and Kmail 1.13.2.
To clasificate my emails, I prefere save and erase the attachement.
When i want erase the attachment in the view of Kmail, in the resumen of the email, that good but i can't erase varios attachment in the same time. 
When i open the email and i want erase varios attachment, Kmail shot off and generate an error.
I lost lot of time with this, because i receive lot of attachement and i can't manipulate them easily.
Tank for your help.
Sorry, mi english is not very good.
see you.
Stéphane
