The interesting parts are missing. Can you reproduce this crash every time ?

If so, it would be useful to install the debug packages for kdepim (or build it in debug mode)

now I installed kdepim-common-debug and reproduced the bug

hm, let's reassign this one to kdepim/messageviewer instead.

Could you please attach or mail me one of these faulty files?

please be carefully with my private data.

Feel free to replace any private data with "x" or any other character as long as you keep the "error".

I anonymized the file and keep the error

Looks like the broken and anonymized vcf never arrived. Can you attach it to this bug report please?

Created attachment 58674 [details]

Thanks. Confirmed with the steps you mentioned.
