Description Ruth 2020-01-16 02:04:37 UTC

SUMMARY
some months ago (2019) this happened and I finally just avoided touching that one message line. It came to the top and I just worked around it. Finally I re-installed my system, openSUSE LEAP 15.1, and the problem was gone. I set up my 2  dozen emails and all was fine until tonight. A different email with an attachment came in, as soon as I click on it, KMail vanishes! over and over again! I really hope I don't have to reinstall my whole system to clear this up!

STEPS TO REPRODUCE
1. Just click on that one email with a newsletter attachment.
2. The whole KMail program closes too fast to click on any Report Bug link.
3. 

OBSERVED RESULT
KMail crashes instantly

EXPECTED RESULT
I see and read the email, and the attached newsletter.

Hi,
Could you paste backtrace ?
Regards

ahm... I am a little naive when it comes to these technical things. In the past there was a notice inviting a backtrace, but since this crash happens so quickly, I'm not sure how I would get a backtrace.



Is that something I have to do at commandline? That's my weak spot. But if you tell me what to do, I'm willing to try.



Thanks,

Ruth

Comment 3 Ruth 2020-01-16 22:06:51 UTC

I was asked for a back trace, and just now when Kmail crashed, I did get a popup offering me a backtrace. It said it was not of any help, but I'll paste it here in case it tells you anything.

You can remove this plugin
/usr/lib64/qt5/plugins/messageviewer/bodypartformatter/messageviewer_bodypartformatter_semantic.so

=> it will not crash.

it was fixed in new version but for your version the better workaround is removing it.

Thank you, Laurent,

I've found that file, however I'm not able to delete it in Dolphin. Is that something I need to do at the command line? What is the exact command to give?

Oh, wait. I could try the Super User file manager because this is down in the root area.



I paused to try that and sure enough, I've been able to delete that plugin. Then I went into KMail, and it took two tries, but now I've been able to delete that email! 

Wonderful! Thanks ever so much!



I will save this information in case I ever need it again - hopefully not, eh?



Blessings & Thanks,

Ruth
