Cannot reproduce karchive building failure

According to https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=50237 karchive fails building

Looking at the log it seems that it times out when running po4a when building bzip2?

https://oss-fuzz-build-logs.storage.googleapis.com/log-bfc610f3-42c1-4d0d-a1e0-0413cdac3805.txt

But I have not been able to get to timeout (i'm assuming there's a non small timeout).

Though it's not clear to me which of the engines/fuzzers is being build in that log, i tried with
python infra/helper.py build_fuzzers --engine afl --sanitizer address karchive
