Seg fault on launch

[Nick Peyton]

The window appears for a split second then exits. If I run from the terminal I get an error:

segmentation fault.

If I run with: gdb /usr/bin/baobab, it crashes but the Window doesn't exit. It just becomes unresponsive.

I tried reporting this at https://gitlab.gnome.org/GNOME/baobab/-/issues but they can't do anything without a full stack trace.

I followed the instructions to create the trace, but it lacks the debug symbols. If I'm interpreting correctly, the baobab binary on Ubuntu 25.04 is stripped, and although Launchpad lists baobab-dbgsym, this debug symbol package doens't exist.

$ sudo apt install baobab-dbgsym
 Error: Unable to locate package baobab-dbgsym

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please execute the following command only once, as it will automatically gather debugging information, in a terminal:

  apport-collect 2133444

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://help.ubuntu.com/community/ReportingBugs.

(You've provided a fair amount of data as text, but not as populated fields; these get added when you use apport tools)

Thanks Chris. That was so easy! Is that enough?

[Nick Rosbrook (enr0n)]

You need to enable dgbsym packages before you can install them https://documentation.ubuntu.com/server/explanation/debugging/debug-symbol-packages/#getting-dbgsym-ddeb-packages.

There is also the debuginfod server, which *should* work, and is described on that page also.

I don't currently have a 25.04 desktop around to test with, but hopefully the above helps you get further debug info.

Stack Trace attached.

I could not remove the extra files, but the stack trace is included and hopefully sufficient.

In case it helps: the flatpak version doens't crash.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Andrei Cherniaev (andrewternity)]

Ubuntu 25.10 the same, just after start
```
$ baobab
Segmentation fault (core dumped)
```

Hello!

Could you check if this is related to this upstream issue? https://gitlab.gnome.org/GNOME/baobab/-/issues/165

Do you have a remote mount currently? If so, does the issue still occur once it is unmounted?

[Nick Peyton (nrpeyton)]

In GNOME FILES (network tab) I connect to my local server via SFTP (sftp://192.168.1.210).

Samba is installed (on this PC), but stopping nmbd.service and smbd.service did not prevent the baobab crash.

I don't have Google Drive, Zee Drive, OneDrive, DropBox, or anything of that nature.
