Clearly, the problem is related to 'spawn'... more precisely here, VTE spawning.
First because Debian Code Searching for "Failed to fdwalk" returned only one result: https://codesearch.debian.net/search?q=Failed+to+fdwalk&literal=1 https://codesearch.debian.net/show?file=vte2.91_0.62.2-1%2Fsrc%2Fspawn.cc&line=647 case SpawnContext::ExecError::FDWALK: error.set(G_IO_ERROR, g_io_error_from_errno(err), "Failed to fdwalk: %s", g_strerror(err));

As my bad habit... I tend to post before taking time to really study the error message. But is there a way to pass ./configure arguments to "dpkg-buildpackage -us -uc"?
