I did not have time to investigate further, but if you have paths you
want me to follow to track this incompatibility bug, I'll be happy to
give a hand.

Investigating a bit further shows it is not an API breakage, but only an
ABI breakage : recompiling scrollkeeper against libxml2 2.6.0 make it work

Okay, I still don't understand how it happened to work properly at some time, 
but it appears that the scrollkeeper package compiled against libxml2 2.6.0 
doesn't work either.

Now, I recompiled bith scrollkeeper and libxml2 with debugging symbols, so 
that backtrace is much more verbose :

This looks like the bug that is being discussed in another thread. John
Fleck just filed this bug report:

and your investigations seem to point to the same thing.

I should point out that with scrollkeeper it is a bit more tricky
identifying the exact problem, since there were a number of memory
management problems in scrollkeeper that have been fixed recently. If
you are building from the 0.3.12 tarball, then you may be able to
trigger some of those (I never could, but they existed in theory).
However, in this case, I think you are looking at a libxml bug.
