Ledger Live Version and Operating System
- tested on Ledger Live 2.40.2
- Platform and version: Manjaro Linux
Expected behavior
Ledger should not crash
Actual behavior
Ledger crashes with the following error:
Internal process killed by signal (SIGSEGV)
Error
at createCustomErrorClass (file:///opt/ledger-live-desktop/resources/app.asar/.webpack/renderer.bundle.js:6447:19)
at deserializeError (file:///opt/ledger-live-desktop/resources/app.asar/.webpack/renderer.bundle.js:6475:35)

at EventEmitter.emit (events.js:327:22)

strace reveals that the last operation before crashing:
1952252 newfstatat(AT_FDCWD, "/sys/devices/pci0000:00/0000:00:02.0/0000:03:00.0/i2c-5/5-0037/ddcci5/idProduct", 0x7ffd03b58b00, AT_SYMLINK_NOFOLLOW) = -1 ENOENT (No such file or directory)
1952252 --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=NULL} ---
In my case this pci device created by the ddcci_backlight module for controlling the backlight on my monitors. It does not have an idProduct file. If I unload the ddcci and ddcci_backlight module ledger-live runs without crashing.
Steps to reproduce the behavior
Use something like the ddcci_backlight module, or some other module that provides pci devices that do not have an idProduct file and try to run ledger-live.
