This is bug 1064762 that has now probably been added to bookworm by a patch

I can work around this here by simply deactivating test, but this kind of
reading of the vtk files I cannot fix here. dune-grid just writes those
files.
The underlying problem can only be fixed in VTK. though. It might affect
other packes.
How should we proceed?
I think it all depends on much effort we[*] are willing to make.
At this point in the life of bookworm (which is 2/3 of its supported
period), there are already at least 60 different ftbfs bugs, so I
would say that fixing the FTBFS problem alone (disabling the offending
tests, if that's your plan and you know how to do it) would be more
than acceptable and a lot better than nothing.
I'll start with that then.
This will leave the main problem, though:
Due to the security fix in expat [1], you will not be able to process
any binary vtk files in bookworm
(e.g. visualize them in paraview) anymore.
To fix that we would need to backport [2] to vtk9
