It's the same. 
I also verified the latest modification done in git and have the same.
Maybe is some error from my system, could also someone else test it?

Dear Allin,
the error is still present.
What kind of other information is necessary in order to eliminate this bug?

Sometime ago there was a discussion about implementing some kind of automatic testing of Gretl, on Ubuntu 14.04 I can test the export/import functions with other programs (Stata, R, Python,  Octave, Julia, not Ox).

Best regards,

In the case that I run the script (gretl_export)from http://lists.wfu.edu/pipermail/gretl-devel/2013-April/004417.html   in Stata the matrix is saved in the user director /home/acer.

This is on the same Ubuntu 14.04.
