--- Comment #8 from Julien Nabet <[email protected]> ---
On pc Debian x86-64 with master sources updated today, I could reproduce this.
After having put a break in:
OTableContainerListener::clear() at
connectivity/source/commontools/TTableHelper.cxx:96
and
OTableContainerListener::elementRemoved(com::sun::star::container::ContainerEvent
const&) at connectivity/source/commontools/TTableHelper.cxx:77
I began to delete tables and found these:
#0 (anonymous namespace)::OTableContainerListener::clear() (this=0x41a3800) at
connectivity/source/commontools/TTableHelper.cxx:96
#1 0x00007f786b1e39ba in connectivity::OTableHelper::disposing()

#0 (anonymous

const&) (this=0x58cedd0, Event=...) at

#1 0x00007f786b2d6709 in

...
Since elementRemoved was called after OTableContainerListener::clear() which
puts m_pComponent to nullptr, we must check if m_pComponent is null before
using it in elementRemoved.
