Cannot load GPX file automatically after creating it QGIS 3.4.7 QGIS 3.6.2

Original Redmine Issue: 22005
Affected QGIS version: 3.6.2
Redmine category:vectors

When I use "save features as..." to create a new gpx file (either from a completely new scratch layer or a shapefile or another gpx file), I get the following error message when QGIS attempts to load file:
QGIS 3.4.7 (long-term release): "Download with "Protocol" source type failed, do you want to try "File" source type?" (choosing "Yes" leads to a non-ending circle, choosing "No" leads to "is not a valid or recognized data source"
QGIS 3.6.2 (lateast release): "is not a valid or recognized data source"

When I choose "Add vector layer..." from the menu and select the file, the file loads normally without any issues. Also, if I uncheck "add saved file to map" during save, there are no error messages (and it does not load either as expected). I tested the workflow on QGIS 2.18 and there are no errors with the same workflow.

(I tried to search to see if this was an existing issue but I could not figure out the search filters, I look forward to the upgrade to github--my apologies in advance if this has already been flagged)

Actually I just came up to report the same thing. The error has been around for a bit and I finally had time today to report it - and thanks for doing this part.

The GPX file is created correctly - it only errors when attempting to load after it is exportd using the "Save Vector Layer as...." dialog box.

When saving a shapefile to a file named test.gpx

The log messages are as follows:
2019-05-07T13:10:19 CRITICAL Invalid Data Source : /media/projects/tsf/payne/test.gpx|layername=test is not a valid or recognized data source.
2019-05-07T13:10:19 SUCCESS Layer Exported : Successfully saved vector layer to /media/projects/tsf/payne/test.gpx

Under the OGR Messages:
2019-05-07T13:10:19 WARNING Cannot find layer test.()
