Looks like something to do with font handling.

The first trouble-shooting step is to run darktable with default configuration. Rename darktablerc (in ~/.config/darktable if a native install, somewhere under ~/.var if a flatpak) to something like darktablerc.bak, then try running darktable.

I've built master on 24.04 (in a VM)_ and it runs without problems, including editing images and opening/closing/changing preferences.

I tried your proposal. The only thing what changed is that I can start the preferences dialog. If I start editing(darkroom) then then application crashes completly. Btw., I used v4.6.1 in ubuntu 23.10 whitout any problems (version 4.6.1). Since 24.04 I have this problems. I tried the version which comes which the ubuntu install packages (v4.6.1), also the version from the ppa https://ppa.launchpadcontent.net/ubuntuhandbook1/darktable (v4.6.1), and also self compiled versions 4.6.1 and darktable-nightly from https://github.com/darktable-org/darktable. I also start the application w/o opencl, always the same result.

and also self compiled

I updated the package install commands on the wiki (https://github.com/darktable-org/darktable/wiki/Build-instructions-for-Ubuntu) to work with 24.04

Nothing todo with font handling. After the crash syslog reports

kernel: darktable[44520]: segfault at 0 ip 0000000000000000 sp 00007fffa5a15a88 error 14 likely on CPU 1 (core 1, socket 0 kernel: Code: Unable to access opcode bytes at 0xffffffffffffffd6

What do you want to tell me? This has nothing to do with the failure!

darktable -d common

Okay, attached the output after selecting darkroom/editing. dt.txt

Both of your backtraces show that the crash happens in pango_coverage_get inside libpango, which "is a library for layout and rendering of text, with an emphasis on internationalization", while trying to compute a Gtk widget's width. That's due to either the font in use or some very odd text being used in the widget.

Since resetting darktablerc cleared up the crash in the preferences dialog but not darkroom view, it's likely that you have a corrupted edit history on the crashing image(s). Do you still get a crash when you start with a completely fresh setup with a newly-imported image that doesn't have a sidecar? Copy some raw image to /tmp/foo.{ext}, then run darktable --configdir /tmp/dt-test /tmp/foo.{ext} (assuming /tmp/dt-test doesn't exist or at least is completely empty).

If that works without crashing, then you should try resetting the edit histories for any images that cause a crash when you start darktable normally -- select them in lighttable view, then use discard history in the history stack module in the right pane.

darktable --configdir /tmp/dt-test /tmp/foo.

If I run 'darktable --configdir /tmp/dt-test /tmp/foo.nef' the application crash immediately after launching darktable_bt_FEB0M2.txt

For now I helped me with installing the flatpak app for finishing my image developing. But this is terrible slow, no opencl support.

I have had exactely the same problem. Solved by going in Settings>Apps>Darktable where i have disabled opengl, and Darktable wors fine. NO more crashes !

I forgot to say, my Darktable is a snap version, installed via App Center.

Obvisealy you mean "opencl". But as I described before it has nothing to do with that for my system

Now I has found a workaround for my problem. The note for a font-libpango-libgtk3 problem left me no peace. So I deinstalled all fonts-noto (in one of the crash reports I see a note to this font family) from my system and now darktable doesnt crash anymore. Curiously enough at other systems that I have running these problems are not exists with istalled noto fonts. So I think the deinstallation of a font group only bypasses the true problem. I think it have to do with the quantity of installed fonts at all.
