            Bug ID: 454257
           Summary: Crash on save of attachment (tar.gz)
           Product: kmail2
           Version: unspecified
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: hpj at urpla.net
  Target Milestone: ---

Application: kmail (5.20.1 (22.04.1))

Qt Version: 5.15.2
Frameworks Version: 5.94.0
Operating System: Linux 5.17.9-2-preempt x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.24.5 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:

Saving an tar.gz attachment. As far as I can see, the existing reports crash
pattern don't match. 

What's probably important to note: this is kmail and friends from the first
full distribution rebuild with gcc12 in openSUSE TW 20220520.

The reporter is unsure if this crash is reproducible.

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