[dochtml] /usr/lib/libntl.so.27(_ZNK3NTL11ZZ_pContext7restoreEv+0x33)[0x7f20158baf83]
[dochtml] /usr/lib/libntl.so.5(_ZN3NTL4ZZ_p4initERKNS_2ZZE+0x2c)[0x7f1dc3b1b6cc]

Perhaps it would be good to add a Build-Conflicts: field then the build would fail earlier.

Could you also take a look at the log yourself first, before emailing this list?
