No problem.  That's what software development is all about.
     
     Now that we finally have all architectures passed the testsuite in
     Debian i just wanted to push some backports and imports in my PPA for
     Ubuntu.
     
     While this was successful for 10.04 (and i therefore could responded to
     the "PSPP-BUG: Request for help..." mail) it gives me testsuite errors
     for 12.04 on i386 that i again cannot reproduce locally.
     
     The failed suites are: 180 181 438
     
     Please see:

     If you can't get a clue out of that i would just try a stupid rebuild.

I don't think a blind rebuild will help.

438 is one of those precision issues probably due to a different compiler or 
math library.
In fact, the comment in the test shows that we've had similar problems before:

 dnl Some machines return .313 instead of .312 for the Point Probability
 dnl (see bug #31611).
 AT_CHECK([sed 's/\.313$/.312/' pspp.csv], [0], [dnl

I think we should just relax the test a bit in a similar fashion.

180 and 181 both relate to reading of openoffice.org spreadsheet files and seem 
to be just warnings.   I wonder why the problem didn't show up on debian?  
Maybe a 
different libxml library?  Since this xml is generated by openoffice itself, 
there's
probably not much we can do if libxml thinks it is wrong.  Perhaps we should 
just 
change the test to ignore the warning.
However if someone who uses Ubuntu can run the tests manually and get a 
confirmation of
the problem it would be better.

Does Ubuntu have newer or older libraries than Debian Sid ?
