It was actually likely introduced by recent changes in the mesa package.

3.8.1-1+b1. I upgraded from Octave 3.6 to Octave 3.8.0-5 on 20140307, then
to Octave 3.8.1-1 on 20140316, then to Octave 3.8.1-1+b1. I also reverted
back to Octave 3.8.0-5, only to verify that the bug was introduced not by
Octave. As you pointed out, that should be the transition of "mesa package"
that is causing the problem.

I am very happy to try to revert back to Octave 3.8.0, since as far as I
can remember, the earliest introduced 3.8 branched worked just fine. I
remember because this release was like a major one, introducing the
official GUI. I'll try that out and let you know.
The backtrace of command "axes" are as follows:

When used "gnuplot", all the plot functions works just fine.

But this does save us from the segfault in psychtoolbox, which seems
to be caused for the same reason:
