Bug 183745

Version:            (using KDE 4.2.0)
OS:                Linux
Installed from:    Debian testing/unstable Packages

I received a mail a couple of days ago and whenever I click on it Kmail just crashes with "A Fatal Error Occurred
The application KMail (kmail) crashed and caused the signal 6 (SIGABRT)."

It only happens with that mail. I tried all other mails without problems. I restarted the application, restarted the pc and there was no difference. It does not matter if i right click or left click on the mail, as soon as it tries to open the mail, Kmail just crashes with the above message.

I tried running Kmail in a terminal by calling /usr/bin/kmail --view /path_to_mail , I got back some messages in the terminal and then again Kmail crashed with the above message but a longer backtrace.

these are the messages I got in the terminal

/usr/bin/kmail --view /home/edhunter/.kde4/share/apps/kmail/mail/inbox/cur/1234029201.5562.MKSgM

*** KMail got signal 6 (Crashing)

sock_file=/home/edhunter/.kde4/socket-siduxbox/kdeinit4__0


this is the backtrace of Kmail if I open it normally and try to open the mail

And this is the trace I get when I open the mail calling /usr/bin/kmail --view /path_to_mail

I have these debugging packages installed

kdebase-runtime-dbg                                      
kdebase-workspace-dbg                                
kdelibs5-dbg                                     
kdepimlibs-dbg
libqt4-dbg       

if I need anything else to get rid of the ?? in the above backtraces please let me know


As far as I can tell there is an attachment with the mail which is in some way corrupt. In case it matters the name of the attachment is winmail.dat. Other people sent mails to that mailing list saying that they get a corrupt file instead of the expected pdf. 

Just to test if it was really the attachment's fault, I opened the mail (/home/edhunter/.kde4/share/apps/kmail/mail/inbox/cur/1234029201.5562.MKSgM) in a text editor and I removed many lines of letters and numbers which I assumed were the attachment and then saved it to a different file and opened it with a double click (application used to open the mail was Kmail view) and it opened just fine.

If you need more information just let me know and I will try to get it for you
