            Bug ID: 416086
           Summary: kmail crashes when opening message (small 7bit empty
                    html table, editor viewable)
           Product: kmail2
           Version: 5.13.0
          Platform: Archlinux Packages
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: kde at a.bitscape.de
  Target Milestone: ---

Created attachment 125014
  --> https://bugs.kde.org/attachment.cgi?id=125014&action=edit
example mime message (7bit, so editor readable)

SUMMARY

kmail crashes every time I try to open this message. I stripped down the real
message (daily report) to this minimal empty html table with one css style.

STEPS TO REPRODUCE
1. kmail --view attached-mime.eml

OBSERVED RESULT

Crash

EXPECTED RESULT

Should show the message window (empty html table)

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 5.4.10-arch1-1
KDE Plasma Version: 5.17.5
KDE Frameworks Version: 5.65.0
Qt Version: 5.14.0

Appeared (I think) with kmail 5.13.0 and still exists in kmail 5.13.1

ADDITIONAL INFORMATION

I tried with all modules switched off in kmail but it still crashes. Host uses
german localization. Original message is a daily report with html and images as
mime multipart. I tried the minimal crash triggering html as mime multipart and
as plain html text. Both crashes kmail here.

If I can provide more helpfull information, please let me know. But I would be
very thankful if someone at least could try to open the mime message and
reports whether this is reproducible or just local here.

Thanks in advance

For convenience, here is the full content payload of the mime file:
-------------------
<html>
<head>
<meta http-equiv="Content-Type"
  content="text/html; charset=utf-8">
  <style type="text/css">
    tr, td {
      border-width: 0px;
    }
  </style>
</head>
<body>        
  <table>
    <tr>
      <td></td>
    </tr>
  </table>
</body>
</html>
-------------------

If you split the css style like this (order does not matter):
-------------------
    tr {
      border-width: 0px;
    }
    td {
      border-width: 0px;
    }
-------------------

Or remove the td tag in the table it works.
