Could not rename file! when writing geolocation data

[pnorman]

This is probably something specific to one of my files, but when you've got 2k images in a directory it's a bit hard to be specific.

Steps to produce:

Load GPX files
Load and correlate images to the 3-4 files

Write to header, altering timestamps, no backup

The error "Could not rename file!" appears

This is the console output
