Monitoring network gives segmentation error

[matus.juraj]

After update to Linux Kernel 4.0.0 Sentinella network traffic monitor stopped working.
In kernel 3.19.0 it worked.

Scenario:
Open Sentinella
Choose a condition: Network traffic
Press Start
Program crashes

Other conditions work.

I use Sentinella 0.9.2-3 and libsysactivity 0.6.5-1

Underlying problem is a segmentation fault in libsysactivity.

Backtrace is:
Application: Sentinella (sentinella), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
