[SOLVED] Meld crash with i3

iterator · 2022-05-16 23:28:00

I'm having an issue getting meld to run on my Arch install. I'm using i3-gaps on lightdm.

The error I'm receiving is a coredump:

Trace/breakpoint trap (core dumped)

Nothing else is displayed (graphical or stdout/stderr).

I suspect there is some dependency I don't have due to using i3, but I'm not sure what. The only related issue I've seen is Meld is displaying horribly in i3. From that post I experimented with changing the icon set around, and ultimately back to the Adwaita default - to no avail.

Any suggestions would be much appreciated!

The error I'm receiving is a coredump:

Well, I guess it would be helpful to look at it.

Thank you. I'm used to a much more manual effort with coredumps. Very impressed with coredumpctl. That being said, I'm not sure what to look at from here.

Looks like https://gitlab.gnome.org/GNOME/meld/-/issues/610
glib certainly wants to print some message (that'd not be the sigtrap) - did you install any python packages w/ pip?
The system is completely updated (no old python packages) - "pacman -Syu"?

strace -fo /tmp/meld.strace /usr/bin/meld

might provide further insight into what files are being tried here (assuming this fits the linked bug)

iterator · 2022-05-19 16:30:52

Thank you, that did provide some insight. It looks like it's failing to find a glib-2 file (gschemas.compiled).

That file does exist under /usr/share/glib-2.0/schemas/gschemas.compiled, so I linked it into /home/user/.local/share/glib-2.0/schemas/gschemas.compiled to see if that would resolve the issue. Now it's getting beyond that point, unable to find some locale files that I have confirmed don't exist.

What meld is this?
https://aur.archlinux.org/packages/meld-git or some flatschpak?

seth · 2022-05-20 15:50:13

I guess the pixbuf message object isn't the critical element (you'd get the untranslated message which is US english)

795155 write(2, "**\nGtk:ERROR:../gtk/gtk/gtkiconh"..., 232) = 232
795155 newfstatat(1, "", {st_mode=S_IFCHR|0620, st_rdev=makedev(0x88, 0x5), ...}, AT_EMPTY_PATH) = 0
795155 write(1, "Bail out! Gtk:ERROR:../gtk/gtk/g"..., 239) = 239

There should be some error message when starting meld now?

iterator · 2022-05-20 19:08:28

Yes, I thought I had included that :-/.

**
Gtk:ERROR:../gtk/gtk/gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Failed to load /org/gtk/libgtk/icons/16x16/status/image-missing.png: Unrecognized image file format (gdk-pixbuf-error-quark, 3)

Interestingly, if I try to start meld from PATH, or using `dmenu_run` from the CLI and then meld, I get the above error. However, if I use dmenu through the Alt + d shortcut, Meld opens fine. It also opens fine if I use `sudo meld`, but when I do that the theme is different (light) than when it's opened through dmenu.

I ran through the permissions changes you mentioned in this seemingly related post. I also updated the mime database, to no avail.

Some environment, possibly even indeed the PATH

diff -pru <(tr '\0' '\n' < /proc/$(pidof i3)/environ | sort) <(printenv | sort)

Diffing the environment pointed out that XDG_DATA_DIRS was exported in my environment. Fault being from an rsync of a home directory on a different system.

Meld has returned to me, and this is solved! Thank you very much for sticking with me through the journey.
