Hmm, I ran integrity test on UBIFS and had this UBI config option
enabled (as well ass emulate write and erase errors options enabled)
yesterday, and it worked fine - not slab problems and UBI was able to
recover from all errors, so the integrity check test worked fine.

But that was the latest UBIFS from the ubifs-2.6.git tree.

We have UBI/UBIFS backport trees, could you try ubifs-v2.6.26.git
please? It has all the UBI/UBIFS patches back-ported. Or you may just
take the patches from ubifs-v2.6.26.git and apply them to your tree.
Please, glance here:
