building kodi fails on hydra

[Thomas Danckaert]

The kodi build on hydra fails due to seemingly random test failures: 
2 to 4 of its 516 tests tend to fail due to a segfault, and it seems 
like different tests fail at each build attempt:

http://hydra.gnu.org/build/1971604
http://hydra.gnu.org/build/1973068
http://hydra.gnu.org/build/1973406

It builds fine on my laptop. Does anybody have an idea what might 
cause this
problem (could it be a hydra resource shortage)?  Does it make sense 
to restart the build once again?
