Spotify SIGSEV

[ironlukas1]

Device

• ThinkPad T15 Gen 1

OS

• CachyOS (Linux kernel 6.18), Wayland (Sway / SwayFX)

Software

• Spotify package: 1:1.2.82.428-1 (AUR)
• spicetify: 2.42.10

Summary

• After applying spicetify, Spotify briefly opens with only three dots in the top-right and then exits with SIGSEGV. Restoring spicetify makes Spotify run normally.

Observed output (most relevant lines):
(spotify:80738): Gtk-WARNING **: …: Theme parsing error: gtk.css:1048:16: 'border-spacing' is not a valid property name (spotify:80738): libayatana-appindicator-WARNING **: …: libayatana-appindicator is deprecated. Please use libayatana-appindicator-glib in newly written code. [0218/014424.650809:ERROR:third_party/crashpad/crashpad/snapshot/elf/elf_dynamic_array_reader.h:64] tag not found fish: Job 1, 'spotify' terminated by signal SIGSEGV (Address boundary error)

Why I think this is spicetify-related

• Spotify launches and runs correctly after running: spicetify restore
• Spotify crashes immediately after spicetify apply
• spicetify config shows injects enabled and preprocesses that modify runtime behavior

spicetify config (excerpt)

• spicetify -v: 2.42.10
• spotify_path: /opt/spotify/
• prefs_path: /home/lunix/.config/spotify/prefs
• inject_theme_js: 1
• inject_css: 1
• replace_colors: 1
• overwrite_assets: 0
• Preprocesses: disable_sentry=1, disable_ui_logging=1, remove_rtl_rule=1, expose_apis=1

Steps to reproduce

1. Install Spotify v1.2.82.428-1 from AUR
2. Install spicetify-cli 2.42.10 and run "spicetify backup apply"
3. Launch Spotify — it opens briefly and then crashes with SIGSEGV
4. Restore stock Spotify (spicetify restore) — Spotify launches normally

Notes on the observed messages

• The GTK css warning ('border-spacing' invalid) and libayatana-appindicator deprecation are warnings and unlikely to cause a native SIGSEGV by themselves.
• The Crashpad ELF error ("tag not found") and the SIGSEGV are the actionable crash indicators; these appear only after spicetify apply in my environment.

What I’m requesting

• Investigation into whether spicetify-modified resources or runtime injections cause a segmentation fault with this Spotify build (1.2.82.428-1).
• Guidance on which patched/overwritten resources to revert if you need to reproduce the crash locally.

Environment details (for debugging)

• Kernel: Linux 6.18
• Window manager: Sway (Wayland)
• Installed dependencies per pacman for spotify: alsa-lib, gtk3, libxss, desktop-file-utils, openssl, nss, at-spi2-atk, libcurl-gnutls, libsm, libayatana-appindicator
• I can provide the full spotify-run.log and the Backup/Patched file listing on request.

If you want more logs attached here, tell me which exact files you need and I’ll paste them.

I am getting the same error on Arch Linux, the relevant issue:

https://github com/spicetify/cli/issues/3695

Update: this was fixed in a subsequent update, either from Spotify or Spicetify (I don't remember)

However I am still concerned, because getting a Segfault indicates that there is something not quite right in the internals
