            Bug ID: 137139
           Summary: Crashes in Kubuntu with 6.4.6:
                    ScSelectionTransferObj:com::sun::star::uno::Reference:
                    Qt5MimeData
           Product: LibreOffice
           Version: 6.4.6.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: heather.ellsworth at canonical.com

Description:
In Kubuntu 20.04 there have been some cases of the following stacktrace and
threadtrace (reported anonymously in the user's background) in 6.4.3, 6.4.4,
and 6.4.5 but not too many really (~40 per release).

However, there has been a very large increase in the same error being reported
(~17k) since users have been updating to 6.4.6.

Could someone please take a look at the following stacktrace and threadtrace
outputs? It's great to get these errors reported anonymously to help find real
issues, but the downside is I have no idea what the user was doing when this
crash occurred.

Stacktrace: https://paste.ubuntu.com/p/Dgw89Hfpqb/
Thread Stacktrace: https://paste.ubuntu.com/p/nVvmPjxZm2/ 


There is also an associated launchpad bug:
https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1897784

Steps to Reproduce:
Unsure what the user is doing when the crash occurs.

Actual Results:
It looks like libreoffice crashes because of this at the top of the stacktrace:
#1  0x00007fc9721f1a9a in KCrash::defaultCrashHandler (sig=11) at
./src/kcrash.cpp:582
        crashRecursionCounter = 2

Expected Results:
Libreoffice should not crash.


Reproducible: Always


User Profile Reset: No



Additional Info:
version is: 6.4.6-0ubuntu0.20.04.1 which is just repackaged 6.4.6.2
