            Bug ID: 467845
           Summary: Kmail crashes when clicking on mail which is gpg
                    signed
    Classification: Applications
           Product: kmail2
           Version: unspecified

            Status: REPORTED
          Keywords: drkonqi

          Reporter: charlemagnelasse at gmail.com
  Target Milestone: ---

Application: kmail (5.22.3 (22.12.3))

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.0-6-amd64 x86_64

DrKonqi: 5.27.2 [KCrashBackend]

-- Information about the crash:
It seems to happen all the time that kmail crashes when clicking on any mail
which is signed (not encrypted) via gpg. Sometimes it helped to just run `gpg
--update-trustdb` but now it seems like it is crashing all the time.

I first see the message but something seems to happen when the signature is
checked (which didn't finish when the mail is displayed first).


In the past, when it was not directly crashing then it was also not accepting
signatures from subkeys (#465551). So it seems some rather recent changes
caused a major regression in kmails gnupg integration.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
