Package: virtuoso-opensource-6.1-bin
Version: 6.1.0+dfsg2-2
Severity: grave
Hello,
it has come to my knowledge that apparently internal database format of
6.1.0+dfsg2-2 has changed in the binary incompatible way with 6.1.0+dfsg2-1.
SQARQL queries fail hinting internal problems when they are executed with
virtuoso-t 6.1.0+dfsg2-2 that uses database files initially produced with
6.1.0+dfsg2-1. The bug has been confirmed on at least i386 and amd64.
For example, if I generate KDE nepomuk index with 6.1.0+dfsg2-1 and later
upgrade to 6.1.0+dfsg2-2, nepomuk starts re-indexing even if it should not and
otherwise behaves weirdly all over the map. However, if I start 6.1.0+dfsg2-2
without any database files and let it create them from scratch, everything
works as expected.
Demonstration of 6.1.0+dfsg2-1 vs. 6.1.0+dfsg2-2 incompatibilities
------------------------------------------------------------------
1) Install virtuoso-minimal 6.1.0+dfsg2-1.
2) Disable nepomuk, remove previous databases files (if any).

$ rm -rf /home/modax/.kde/share/apps/nepomuk/repository/
3) Start nepomuk. Let it create an index.
4) Execute a simple query. Everything is just fine here.

5) Stop nepomuk, make sure it stops virtuoso-t as well.
6) Upgrade virtuoso to 6.1.0+dfsg2-2:
libvirtodbc0 virtuoso-minimal virtuoso-opensource-6.1-bin
virtuoso-opensource-6.1-common
$ sudo aptitude dist-upgrade
7) Start nepomuk. It starts virtuoso-t and begin reindexing again (albeit
unsuccessfully). What is more, at that point, nepomuk ceases working properly
in general.
8) Execute the same simple query as in (4). It fails...
