Description Chani 2010-01-27 00:32:34 UTC 
Application: kmail (1.13.0)
KDE Platform Version: 4.4.60 (KDE 4.4.60 (KDE 4.5 >= 20100120)) (Compiled from sources)
Qt Version: 4.6.1
Operating System: Linux 2.6.30-ARCH i686

-- Information about the crash:
I've got three identical emails from google groups about a spammer attempting to send mail to my moderated group. all three crash kmail every time.
I'm using 4.4 branch from.. sometime during campkde.
I haven't tested any of the older message-pending emails yet (google groups is spammy, but I know they didn't crash trunk before).

I can forward the email to someone from the gmail web interface if that's useful, but I dunno how much data it'll preserve.

The crash can be reproduced every time.

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

Comment 1 Chani 2010-01-27 00:40:02 UTC 
the older message-pending mails crash it too. they don't look unusual in gmail, just a plaintext email with an unnamed attachment containing the pending message.
Comment 2 Dario Andres 2010-01-28 23:02:47 UTC 
The backtrace seems related/the same as bug 186502.
I have seen other crashes mentioning a "unnamed attachment" (but I can't find them)

Comment 3 Julian Bäume 2010-02-04 09:47:23 UTC 
moin,
I think, I experience this bug, since upgrading to KDE >4.3.60. I played around with a message crashing kmail. I deleted the message and opened it from my wastebin (which is a local folder, not stored on IMAP) and there it doesn't crash. Then I copied it back onto my IMAP account (into any folder) and after opening the mail, kmail crashes with exactly this backtrace, again.

I can also view this test-message fine on another computer running KDE 4.3.4 on both, IMAP and local folders. I can confirm that this mail contains an attachment with 0 byte size. At least kmail reports it to be 0 byte. In my local trash folder it isn't. In my stable KDE install, it also shows 0 byte in IMAP folders and non-zero, when viewed from a local folder.

May be this helps, tracking this down.

bye then

Comment 4 Julian Bäume 2010-02-04 10:03:08 UTC 
hey,
I played around with this some more and found a work-around. It only crashes when opening the mail with "View -> Attachments" set to "Smart". Everything else works fine. It also doesn't crash when the message is open and I change the view-setting to "Smart".

I was only able to reproduce this with the "original" message. I tried all forms of "forwarding" kmail offers and it changed the mail in a way, that it didn't crash anymore.

I'll disable "Smart"-view for now and see if some other mail still produces this bug.

bye then
