--- Comment #7 from Terrence Enger <lo_bugs at iseries-guru.com> ---
Created attachment 166782
  --> https://bugs.documentfoundation.org/attachment.cgi?id=166782&action=edit
backtrace from call indirect through 0x0

I followed the steps of comment 6.  For specificity:
  - at step 4), the program prompted "... save changes?".  I clicked <No>.
  - at step 6), I deleted tables in the order of comment 0 step 3.
    The crash happened at step 3.b., delete table Verträge.

This observation is from a local build of commit 5219c6bd
(2020-10-24), built and running on debian-buster.


>From the backtrace (rewrapped):

    #14 0x00007f781b204a57
        in (anonymous namespace)::OTableContainerListener::elementRemoved
            (com::sun::star::container::ContainerEvent const&)
            (this=0x5581da160750, Event=...)
        at /home/terry/lo_hacking/git/libo6/
            connectivity/source/commontools/TTableHelper.cxx:78

That source line reads:
                m_pComponent->refreshKeys();
m_pComponent is 0x0.


I am adding keyword haveBacktrace.
