there must be another problem on your computer.
The error code as far as I could read from your screenshot says "critical process died", which means a system critical process crashed, not TSVN. Also: a normal process like TSVN is can not cause a BSOD at all, ever! Only drivers and critical processes can do that.
Also, Windows is very stable in regards to BSODs, which means that the most likely reason for a BSOD is always faulty hardware. Since this happens when you try to commit bigger documents I would suspect the harddrive/SSD - so backup your data NOW and then run hardware check tools.
