Panick on failed svg assertion

[ggmueller]

cosmic-launcher fails for me when searching for 's'

It seems an unexpected svg might be the issue:

[iamkartiknayak]

Is this still a issue?

[ggmueller]

Yes, it still is on cosmic-launcher 0.1.0~1743023214~24.04~d43746c

[mmstick]

Do you know which SVG caused this?

[ggmueller]

Unfortunately not, do you have an idea how I could find the right one?

[fmhirtz]

I did an strace on the process, and I appear to have a couple of SVGs that trigger this. If I search with 'se' it crashes, as well as just 'w'. If the SVG that's tripping us is the last one that the process opened, then the ones that I'm seeing are:

openat(AT_FDCWD, "/usr/share/icons/Cosmic/scalable/apps/multimedia-volume-control.svg", O_RDONLY|O_CLOEXEC) = 43 statx(43, "", AT_STATX_SYNC_AS_STAT|AT_EMPTY_PATH, STATX_ALL, {stx_mask=STATX_TYPE|STATX_MODE|STATX_NLINK|STATX_UID|STATX_GID|STATX_MTIME|STATX_CTIME|STATX_INO|STATX_SIZE|STATX_BLOCKS|STATX_MNT_ID, stx_attributes=STATX_ATTR_IMMUTABLE, stx_mode=S_IFREG|0644, stx_size=1410, ...}) = 0 read(43, "<svg version=\"1.0\" viewBox=\"0 0 "..., 1410) = 1410 read(43, "", 32)

openat(AT_FDCWD, "/var/home/<user>/.local/share/icons/Neuwaita/scalable/apps/org.gnome.Evince.svg", O_RDONLY|O_CLOEXEC) = 43 statx(43, "", AT_STATX_SYNC_AS_STAT|AT_EMPTY_PATH, STATX_ALL, {stx_mask=STATX_ALL|STATX_MNT_ID|STATX_SUBVOL, stx_attributes=0, stx_mode=S_IFREG|0644, stx_size=25500, ...}) = 0 read(43, "<?xml version=\"1.0\" encoding=\"UT"..., 25500) = 25500

I'm not set up to get a core at the moment, but might be able to do that if needed.

[mmstick]

@fmhirtz Perhaps you could provide that SVG

@mmstick This is possibly related to https://github.com/linebender/resvg/pull/948
