"Cannot access a disposed object" after clicking image in [inferencer] gallery panel

[richardm1]

What happened?

Drag-and-drop image from the gallery (right side of inferencer) into the prompt window:

Seems to happen at random. I can tell it's about to happen when I flip to an existing generation tab and the model (checkpoint) selector is blank.

Note the .PNG generation appears to be fine (i.e. no metadata corruption). Drag-and-drop of said image works if I restart SM.

Steps to reproduce

See above.

I think I've tracked it down.

2025-09-02 20:07:46.5540|DEBUG|StabilityMatrix.Avalonia.Services.InferenceClientManager|Model index changed, reloading shared properties for Inference
2025-09-02 20:07:46.6364|INFO|StabilityMatrix.Core.Services.ModelIndexService|Loaded 12 models from database in 383.47ms

I'd just deleted a checkpoint (not the one I was using at the time).

I'm NOT messing with any models tonight and still getting this when clicking on an image in the inferencer gallery.

Still present in 2.15.2. Can't zero-in on what [sequence of] actions causes this. This time I clicked on a photo in the inferencer's gallery (vertical scroll list on the right).
