Bug#788101: [qgis] Crashes in initialization of spatialite

[Jan Hudec]

Package: qgis
Version: 2.8.1+dfsg1-1+b1
Severity: important

--- Please enter the report below this line. ---

Any attempt at connecting to spatialite database produces segmentation fault. 

Downgrading to qgis 2.4.0 does NOT help, but it used to work. On the other 
hand, spatialite's own tools seem to work, so I am not sure whether this is 
qgis or spatialite bug.

Backtrace is:

Program received signal SIGSEGV, Segmentation fault.

(gdb) info locals
No locals.

This happens immediately at any attempt to connect to spatialite database, 
rendering the spatialite backend unusable.

I installed spatialite debug symbols for the above backtrace, but it does not 
seem to show much extra data. I can't find debug data for the other binaries.
