Manual testing - itemmodeltest crashes

The manual test itemmodeltester crashes when selecting the bars in the graph. It happens as a result of an assertion error:

• ASSERT failure in QList::at: "index out of range"

Steps to reproduce:

The crash happens any time you attempt to select one of the bars in the graph. This can be by left-clicking the graph directly, or by left-clicking the cells in the table below the graph.

Expected behavior:

The application should not crash when selecting a bar in the graph.

Observed behavior:

The application crashes when selecting any of the bars in the graph. This includes selecting them indirectly via the table.
