Valide trunk crash when I try to close a file with changes (saving them)

[Monkey]

Valide trunk crash when I try to close a file with changes (saving them). Fresh Ubuntu 11.04 (alpha2) and with a fresh Valide trunk.

Program received signal SIGSEGV, Segmentation fault.

Sorry but I can´t fix this. Could You review this please?
P.S: I think the bug is in source-buffer.vala and split-source-view.vala
