Hi all,

I’m not sure whether this belongs here or on GitHub.

I just installed today’s preview (`4.13.0-2021-08-31 r30139 / 62817ae`

) and then the TorchIO extension using the new, very nice Extensions Manager. I am on Ubuntu 18.04.

When I open the `TorchIO Transforms`

module and I click on the `Input volume:`

selector, Slicer crashes. It seems to be related to `vtkDebugLeaks`

.

This is the output of the console I used to open Slicer:

```
