redshift-gtk sometimes segfaults on startup

[jayhendren]

I'm running redshift-gtk via a systemd user service I'm using a config file to store my coordinates instead of connecting to location services. Sometimes, when I log in, redshift-gtk will start and immediately segfault:

Mar 23 22:26:23 birdhouse systemd[1156]: Started Redshift display colour temperature adjustment (GUI).

This issue occurs on maybe 20% of logins, and I haven't been able to trigger this issue when manually running systemctl --user start redshift-gtk after I log in, so perhaps this is a timing bug?

Here is the core dump. Sorry I had to compress the .lz4 archive into a .zip archive; GitHub wouldn't allow me to attach an .lz4 archive.

core.redshift-gtk.lz4.zip

[imrehg]

It seems I hit the same thing (the stack trace is the same). On first login redshift-gtk starts fine, if log out and log back in, reliably does not start up at all. Usign ArchLinux + XFCE4.

[jonls]

This seems to be a segfault that is triggered inside of libgtk-3.so.0. I don't think there is anything we can do about this from Redshift. I think this would probably be more useful to the GTK developers who may be able to provide a fix. I'm closing this issue for now.

[joostrijneveld]

Was there a follow-up issue filed at GTK? I cannot find any, but I may be overlooking it

[jayhendren]

@joostrijneveld Not that I'm aware of.

[finex]

Unfortunately the segfault is still an issue after six years.
