I was unable to reproduce the problem using the code you gave me,
on a Debian system using the binary you mentioned below. I used an
old wrfout file I had.

Unfortunately, I don't have access to an Ubuntu system. Has this
Debian binary worked on other systems with this same code?

One thing I did notice, which I don't think has anything to do with the
cape_thermo issue, but is still an issue. In your "filter2d" code, you have the calling sequence:

      SUBROUTINE filter2d( a, b, nx , ny , it)

in our version of the code, which was taken from the original wrf_user_fortran_util_0.f
code, we have the calling sequence:

      SUBROUTINE filter2d( a, b, nx , ny , it, missing)

It's possible that your wrf_user_mass.ncl script is getting our version of filter2d rather than your version.
You may want to rename it, just in case. (Don't rename it to dfilter2d, as we have a routine by this
name too.)

Do you know what kind of mods were made to the wrf_user_fortran_util_0.f file?

Does the code crash the first time it tries to call cape_thermo?
