This sounds to me like your font is either incorrectly claiming to be
monospace but, in fact, isn't, or your font is not getting picked up and
used.

In my X defaults, I have:

XEmacs.default.attributeFont: Bitstream Vera Sans Mono-15

For me, on a similar platform (Debian, but otherwise similar software),
tabs (and other spacing) work as expected.
