fbterm segfaults with the original vi editor

[yurikornilov]

Segmentation fault occurs when using the original vi editor (http://ex-vi.sourceforge.net/ - this is the default vi variant in Arch Linux).
The easiest way to reproduce the bug is the following:

fbterm
vi /tmp/newfile
ia

It seems that segmentation fault occurs when inserting in the beginning of the line (so creating a new file always causes segmentation fault).

PS. Other editors (vim, nano) work without errors.
