GPS positioning stops working after a random duration

[slowcyclist]

When an app actively uses gps (e.g. PureMaps, SensorStatus ...), I find that the location is no longer updated after a random time ranging from a couple of minutes to well over one hour.

When that happens
-the app no longer receives position updates, as if you were not moving anymore (the app itself is fine, it's not frozen),
-the white location icon is no longer visible in the top toolbar, and if you open the positioning setting panel, positioning is "on" but no longer green and you can't toggle it.
-SensorStatus reports "AccessError"

The only way to recover gps positioning is to reboot the phone. Needless to say this bug is particularly annoying when you are depending on your phone for routing while driving. It's also quite frustrating since PureMaps would route me for hours without any problem on my previous phone (Xperia X under 20.04).

When the loss of positioning occurs, the journal shows :
Mar 01 17:02:39 ubuntu-phablet systemd[1]: lomiri-location-service.service: Main process exited, code=killed, status=11/SEGV
Mar 01 17:02:39 ubuntu-phablet systemd[1]: lomiri-location-service.service: Failed with result 'signal'.
Mar 01 17:02:39 ubuntu-phablet systemd[1]: lomiri-location-service.service: Consumed 1.165s CPU time.

and the service invokes ExecStart=/usr/bin/lomiri-location-serviced --bus system --provider gps::Provider --provider remote::Provider

so it's lomiri-location-serviced which segfaults after a random duration, requiring reboot.

I did not worry too much about the issue earlier because I do not use the GPS heavily, but I believe this issues was already present when got my FP5 back in October. I'm presently on daily channel, running 24.04-1.x (2026-02-13/2), and lomiri-location-service is 3.3.0+0~20250628184827.14+ubports~dev~1.gbp8c98a8

Am I the only one having this issue?
