Changes between Initial Version and Version 1 of Ticket #20962, comment 4

initial	v1
1	1	I've experienced the issue with any Garmin-generated waypoint file recently. I haven't tested with non-Garmin files. I've uploaded an example.
2	2
3		While testing to confirm just now, I realized that my workflow is a bit different from what I originally listed. I'm normally only interested in the "Markers from..." layer, so I always delete the other layer that's created when I open a GPX file (named after the file). If I leave this layer in place, I can change the colour of the markers layer successfully with no errors. It's only when I delete the GPX layer that I get the exception when changing the colour of the markers. I'll update the steps to reproduce.

I'm normally only interested in the "Markers from..." layer, so I always delete the other layer that's created when I open a GPX file (named after the file). I'm actually not even sure why there are two layers or what this other one is intended to be used for.
