tdf#132388: add unit test
I hope that this performance test is OK. I chose 20 s threshold, as
it works much faster on my system (under 4 s); it shouldn't be much
slower elsewhere; and both the original bug, and the regression that
followed the initial fix, made it execute orders of magnitute slower
(I expect hours on fast systems).
