Description grum999 2023-08-17 17:40:58 UTC 
SUMMARY
The first file I open in Krita, whatever the format (jpg, png, kra) generate the following message in terminal:
```
QAbstractItemModel::endInsertColumns:  Invalid index ( 0 , 101 ) in model KisAnimTimelineFramesModel(0x5607b0855610)
```

STEPS TO REPRODUCE
1. Start Krita from terminal
2. Open a file

OBSERVED RESULT
- An invalid index message related to KisAnimTimelineFramesModel is displayed
- Next files opened don't generate message

Note: if Animation Timeline docker is visible, there's no error message 

EXPECTED RESULT
- No error message?

Opening an animation file with 75 frames (0 to 74)  generate a different message :)
```
QAbstractItemModel::endInsertColumns:  Invalid index ( 1 , 75 ) in model KisAnimTimelineFramesModel(0x55f8e4ef8380)
```
Comment 2 Emmet O'Neill 2023-08-18 21:30:17 UTC 
Yep, you're right. 

I'm not sure why this is happening yet, but it'll be on my list of things to look into next week.

Thanks for the report as always grum!

Fix a model warning in KisTimeBasedItemModel

There were two issues:

1) KisTimeBasedItemModel::columnCount() could return the value that
   has already changed in the image without calling to
   begin/endInsertColumns. That is not really welcome by Qt.

2) In KisTimeBasedItemModel::setImage() we reset the model (and therefore
   updated its columns list), but didn't update m_d->numFramesOverride,
   which caused double insertion of the columns in
   slotPlaybackRangeChanged() a bit later.
