This looks like Debian Bug #785091 (https://bugs.debian.org/785091)

SpatiaLite 4.1.1 on Debian testing/unstable is now built with Proj 4.9.1
causing issues with the non-threadsafe spatialite_init() method.
spatialite_init_ex() should be used instead. See the related discussion
on the SpatiaLite Users list:

https://groups.google.com/d/msg/spatialite-users/v-RCCrx5GoM/OruNkGnZG-IJ

To fix this in Debian we need to transition from GDAL 1.10.1 to 1.11.2
to get the spatialite_init_ex() support in GDAL, and we also need to
transition from SpatiaLite 4.1.1 to 4.2.1 but the final release is not
out yet. GDAL will use spatialite_init_ex() for SpatiaLite >= 4.1.2.

Kind Regards,

Bas
