            Bug ID: 481228
           Summary: Crashes when trying to edit a failed mail from Outbox
    Classification: Applications
           Product: kmail2
           Version: 5.24.4
          Platform: Manjaro
                OS: Linux
            Status: REPORTED
          Severity: crash
          Priority: NOR
         Component: commands and actions
          Assignee: kdepim-bugs at kde.org

  Target Milestone: ---

**Disclaimer**: I tried to follow KDE guideline (
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
) to provide backtrace, but my lack of familiarity with gdb and poor KDE
documentation lead to waste of my time and getting stuck at `(gdb)` after
running `gdb kmail ~/core.core`. No GUI window openned, and typing `help` told
showed some commands such as "status", but none of them were valid commands and
they resaulted in gdb error! Well, I tried! If there is anything I can provide,
please give me a step-by-step guide and I will follow and report back. Until
then, this bug report is to  the best of my efforts.

SUMMARY

Opening the signed (not encrypted, just signed) from the outbox causes crash.

I was sending an email with a ZIP attachment which contained a js file. KMail
failed to send the email and put it inside Outbox. This is the error I got:
"Failed to transport message. Server error: Rejected: forbidden file type in
zip attachment: test/static/script.js"

I opened Outbox, right-clicked on the email and pressed "Edit as new" and it
crashed. removing the singing solves the issue. It is possible that its is also
due to having a Zip file.

STEPS TO REPRODUCE
1. create an email that will fail (add a javascript file to a zip file and send
to gmail)
2. when the sending fails, it goes to outbox. open the outbox
3. right-click and select "Edit as new"
4. observe the crash

OBSERVED RESULT
Crash.


EXPECTED RESULT
Not to crash
