            Bug ID: 143454
           Summary: Crash after dragging and dropping a table or query
                    from treeview to sheet in Libreoffice Calc data
                    sources view
           Product: LibreOffice
           Version: 7.1.4.1 rc
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
I tried to drag and drop a query or a table from LO Calc data sources treeview
to the lower workssheet table. This causes an immediate crash of all running LO
programs (Calc, Writer, Base). 

I tested the effect with a fresh installation of LO 7.1.4.2 on Win7 without any
additional MySql Connectors or other stuff. Crash can be produced with default
Bibliography database as the simplest case.

I tested it with installed MySQLConnectors from mysql or mariadb and my own
database on remote system while dragging and dropping  my own queries and
tables. In this situation, I noticed the problem the first time. But the fresh
install with default Bibliography is the simplest case to reproduce the bug. 


Steps to Reproduce:
1. In Libreoffice Calc: menu View -> Data sources. Opens the treeview with the
default database Bibliography.

2. Drag and drop the table biblio to the lower spreadsheet.

3. In 90% of all cases, the drag and drop icon is visible. In these cases, all
opened libreoffice programs (including Calc itself, but also Writer or Base)
are crashing immediately after drag and drop and a file recovering report is
displayed. In the remaining 10% of the cases, when no drag and drop icon on
mouse cursor is visible nothing happens. But the drag and drop action is also
not executed. In contrast to that, the drag and drop action from the loaded
data table in the right upper table view to the spreadsheet always works as
expected with a visible drag and drop icon. 


Actual Results:
Program crashes after drag and drop a table or query from data sources treeview
in LO Calc to the lower spreadsheet. 

Expected Results:
The table content (loaded records from database) should be copied to
spreadsheet as text. 


Reproducible: Sometimes


User Profile Reset: Yes


OpenGL enabled: Yes
