iota crashes after C-A/C-E when the buffer is only one line

The editor crashes due to a rust_panic caused by an out of bounds access on a Vec whenever move-beginning-of-line (C-a) or move-end-of-line (C-e) is used in a buffer with no newlines.
thread '<main>' panicked at 'index out of bounds: the len is 0 but the index is 0', /Users/rustbuild/src/rust-buildbot/slave/nightly-dist-rustc-mac/build/src/libcollections/vec.rs:1346
The issue seems to be with buffer.rs in get_line_index_backward and get_line_index_forward: nlines is an empty Vec when the buffer contains no newlines. The subsequent access to nlines[offset] on line 275 and 334 causes the panics.

Thanks for the report! Will try get this fixed asap!

This doesn't crash anymore, however C-e does nothing at all when you are on a line without a newline at the end of it.
