Description Christian 2019-03-23 22:11:35 UTC
Application: kmail (5.7.3)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-46-generic x86_64
Distribution: Ubuntu 18.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:
In KMail's list of mails in the inbox, I clicked on one mail that contains a vcard.vcf attachment. Kmail crashes instantly, before I see any parts of that actual mail. As a side-effect, I can't get rid of this mail because before I can delete or move that mail, I have to select it by clicking on it, but this crashes kmail as mentioned.

The vcard.vcf attachment of that mail contains a somewhat larger list of multiple adresses - approx. 100 addresses inside that vcard file.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Comment 1 Christian 2019-03-23 22:29:52 UTC
Just for completeness: I'm running LANG=de_DE.UTF-8. When starting kmail from the command line, I get the following message approx. 100 times (i.e. once for each address in the vcard.vcf):

org.kde.pim.kcontacts: address format database incomplete (no format for locale "en" found). Using default address formatting.
org.kde.pim.kcontacts: address format database incomplete (no format for locale "en" found). Using default address formatting.

Example vcf that crashes my kmail instance

With the attached (dummy) vcf file that contains two entries, I can reproduce this crash every time. To reproduce: Save the attached all.vcf file somewhere; create a new message to myself with this file attached and send the message; receive the message and left-click on it -> crash.
