XnViewMP crashes on Batch Rename

[laurent45654]

1.11.6, macOS

This is new issue as far as I can tell as it wasn't happening at all before, while now it's quite common.

I can't replicate it systematically but the steps are simply:

- Select multiple pictures
- Click Batch Rename (I have the button in my toolbar)
- Set the Name Template
- Click Rename

And it crashes. One possible reason I noticed today is that one of the file that was selected had been deleted (but XnView hadn't refreshed yet).

Unfortunately I cannot share the crash dump since it's binary and I don't know what it includes.

Could you send it with crash dialog, or send it to me

That's not necessary actually as I found how to replicate it consistently:

- Open a folder with images in XnView and select them all
- Open the same folder in Finder
- Delete one of the images in Finder
- Immediately switch to XnView (before it has time to refresh)
- Open the Batch Rename tool (specifically I use it with a "Name template")
- Click Rename

For me it crashes every time when I do this. I'm guessing it's trying to process the image that has now been deleted.
