Justification: fails to build from source (but built successfully in the past)

Dear Maintainer,

During a ratt run for src:ossp-uuid, I see
  2024/09/26 16:46:59 Building package 68 of 123: gscan2pdf

It's currently 2024-09-26T17:03:48+02:00,
and the process tree looks like this:

and hasn't changed the last few times I looked (3001252 is a thread).

This is a ratt run, so the build is in a schroot.
I created the chroot this morning, so no funny business there.

I SIGINTed the test, and the tests continued.
The same happened with t/133_save_tiff_with_error.t later.
The same happened with t/1612_import_TIFF_with_error.t later.
The same happened with t/1626_import_PDF_with_error.t later.
The same happened with t/1632_import_ppm_with_error.t later.
The same happened with t/213_rotate_with_error.t later.
The same happened with t/243_threshold_with_error.t later.
The same happened with t/253_negate_with_error.t later.
The same happened with t/263_unsharp_mask_with_error.t later.
The same happened with t/273_crop_with_error.t later.
The same happened with t/283_to_png_with_error.t later.
The same happened with t/377_user_defined_with_error.t later.
One has to wonder if the error is that it hangs.

I'm attaching the build log.

Don't think this is the same as #1012250 since that's autopkgtests.

Naturally,
2024/09/26 17:21:32 building gscan2pdf failed: exit status 2
but I'm forced to assume this is due to whatever flakiness in the test?

I reproduce this behaviour with a plain sbuild -d unstable gscan2pdf
so it's not the fault of the new src:ossp-uuid.

Best,
