Description beirne 2004-07-14 14:17:51 UTC

Version:            (using KDE KDE 3.2.91)
Installed from:    Compiled From Sources
Compiler:          gcc (GCC) 3.3.4 (Debian 1:3.3.4-3) Running Debian unstable.  
OS:                Linux

Whenever I try to view the full source of an email message by selecting "View Source" from the kmail menu or hitting the "V" key kmail crashes immediately.  I have pasted a backtrace below.

Comment 2 Till Adam 2004-07-15 11:02:19 UTC

Does this happen with any mail, or just some? If the later, can you attach one of those mails to this bug report, please, so I can try to reproduce and fix the problem?

Comment 3 beirne 2004-07-15 13:29:11 UTC

Created attachment 6684 [details]
Kmail crashes when a "View Source" is done on this message

The body of this sample message is empty, but kmail also crashes when viewing
the source of some messages with content.

Comment 4 beirne 2004-07-15 13:30:19 UTC

It turns out that only some messages cause the crash.  Kmail doesn't crash, for example, when I try to view the source of the bug update notifications.  I tried moving a crashing message from an mbox folder to a maildir folder and got the same behavior.  I also took a brief look at each type of message but didn't see an obvious difference.  I'm hoping it becomes clearer with the attached message, which causes kmail to crash when viewed.

Comment 5 Till Adam 2004-07-15 18:20:46 UTC

Thanks for the test mail. I can't reproduce the crash with current cvs (3.3 branch, not 3.2), so hopefully the issue you are seeing has been resolved. Is there a chance that either of you could verify that the issue is indeed fixed by compiling kdepim from cvs, or maybe testing with the beta2, once it is out?

Comment 6 beirne 2004-07-19 14:30:53 UTC

I've had bad luck getting the beta to build.  I may end up waiting for beta2 to test again.

Comment 7 A. Pfaller 2004-08-05 00:38:30 UTC

Also happens with self compiled kmail from current KDE_3_2_BRANCH.
Backing out patch from 1.99.2.5 to 1.99.2.6 of kmcommands.cpp fixes
this. I got the crash with all mails I tried (5 from different mbox
folders).

Comment 8 Adeodato Simó 2004-08-08 15:19:56 UTC

In KDE_3_3_BRANCH, this was fixed on rev. 1.156 of kmcommands.cpp. I'm hereby asking for the backport of this fix to 3_2_BRANCH. I can do it myself if developers are short of time with 3.3 polishing.

Thanks,

Comment 9 Till Adam 2004-08-08 16:50:39 UTC

I'm told there probably wont be another 3.2.x release and the crash is fixed in 3.3 and later, I'll therefore close this bug. We don't have the resources to maintain more than one stable version and 3.3 is the new stable version (or will be very shortly). Thanks for understanding.

Comment 10 Till Adam 2004-08-09 15:28:17 UTC

*** Bug 86849 has been marked as a duplicate of this bug. ***

Comment 11 Michael van Gemmern 2004-08-09 16:01:16 UTC

Because my example isn´t shown here:

my kmail1.6.82(kde3.3beta1) crashes when "charset=us-ascii" is in the header of the mail. Three is no problem with any other charset. Mine is iso-8859-15 (locale).

Comment 12 Siddhesh Poyarekar 2006-04-18 12:48:34 UTC

Seems like this bug has crept up again. I am getting the same error, this time on the following specs:

i386 binary package dist-upgrade'd from debian sid
KDE 3.5.2
KMail 1.9.1
Debian unstable

This happens with all the random messages I tried on.

Steps for reproduction:

1) Start KMail
2) Click on "View > View Source" menu


Here's the backtrace, if it's useful at all:

Comment 13 Michal Seweryniak 2006-04-20 20:58:11 UTC

I've got the same crash as in Comment #12 at Opensuse 10.0 + KDE 3.5.2 + Kmail 1.9.1 (from Suse RPM). It happens for every message. 
To reproduce: 
before you go to menu View/View Source, first you need to switch off the message preview panel in Kmail configuration. The crash doesn't happen when the message preview panel is on.

BTW
Why the status is 'RESOLVED'? It's unresolved in my opinion.

Comment 14 Siddhesh Poyarekar 2006-04-20 21:10:37 UTC

> BTW
> Why the status is 'RESOLVED'? It's unresolved in my opinion.

I guess the status is such because the bug was closed previously. I
guess it needs to be re-opened or a new bug filed. Strange that none
of the maintainers have responded yet.

Sorry about not responding earlier, I had reopening this bug in mind, but I forgot. By the way, I was able to reproduce the bug with using the description in comment 13. Thanks for that Michal.
