Session loading fails to parse a log file in NMEA format.

[bartosomail@…]

I saved a session which includes a layer for a track log in NMEA format, choosing the option to save gpx data as local file. During session loading, an error notification window "Error loading layer" pops up, with message "Could not load layer 'xxx'. Error is: Parsing data for layer 'xxx' failed".

The same NMEA log loads normally if I instead choose to include gpx data in session file.

Can you please attach your status report, plus your session and NMEA files? Thanks.
