Bug#709779: [synfigstudio] Segment Violation after Synfig core update

[Fenix]

Package: synfigstudio
Version: 0.63.05-1
Severity: grave

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

After the update of Synfig core to 0.64, Synfigstudio break down with a 
segmentation fault.

---
Program received signal SIGSEGV, Segmentation fault.

0x083a42f9 in studio::WorkAreaTarget::next_tile(int&, int&) ()
---

I've clean and recreate ~/.synfig.

I've seen that a synfigstudio update to 0.64 is imminent in testing. 
Maybe it fix the problem... but would be Synfigstudio depend of core 
0.63 as maximum and not permit to update to 0.64?
