Version: (using KDE 4.3.1)
Installed from: SuSE RPMs
I receive an unencrypted email with an unencrypted attachment (tested: .rar, .ods, .docx filetypes) using an IMAP account.
I can read the email just fine, attachments are listed as usual. I know the attachment is unencrypted because I sent it myself from another (web based) account.
Clicking or right-clicking the attachment and choosing to save the attachment opens KDE4 file-picker.
Choose 'Save' to save it wherever.
Kmail asks two questions on after the other. From memory the text is:
First: 'Attachment part <name> is encrypted. Do you want to keep the encryption?' (Yes, No)
Second: 'Attachment part <name> has a signature. Do you want to keep the signature?' (Yes, No)
If I click Yes to either of these questions, kmail crashes. If I click No to both, kmail saves a zero byte file.
If I instead choose to open the attachment with the associated application (eg Ark, OpenOffice) from within kmail without saving it, the attachment opens in the application just fine.
I have 3 Identities, each with 1 IMAP account each. My default identity had encryption set up using gpg. Before this, saving attachments used to work. Not sure if this was the cause of the problem so I removed all encryption stuff from that identity.
Problem still happens on the default identity, and it also happens on any other account/identity, even though those have never been set up to use encryption.
Using kmail standalone, from the openSUSE 11.1 KDE4 Factory repos, 32bit arch.
Forgot to say, I posted on the opensuse forums here: http://forums.opensuse.org/applications/421501-kmail-thinks-attachment-encrypted.html
I can confirm this on Arch Linux current 64bit KDEmod 4.3.1 and previous. I use just one identity and it doesn't have encription set up.
