 Perhaps the following helps. I tried that test on a pristine patched 4.6.2
 and it passed. Then I ran `make ptestlong` and now it fails -- also when
 run individually. So that would point to ptestlong changing something.
 Does it rewrite/invalidate some maxima cache somewhere?

 It messes something in ~/.sage/maxima_commandlist_cache.sobj on my
 computer.

 Did not took the time to investigate it further.

 If you delete that file it runs again.

 > * errors: I realized I was not quite correct. Errors about inconsistent
 assumptions now get reported differently too.

 I was aware of the inconsistent assumptions, I guess that's not a big
 problem.

 > * the same applies to the python_to_ecl error message: By using a
 "...%s..."%... in constructing the error message, you are slowing down the
 exception propagation. People can easily figure out which type it failed
 on by letting python drop into a debugger (%pdb 1) that allows them to
 analyze the local environment upon exception raising. (OK, you have to go
 "u" one time because pdb isn't terribly helpful with cython functions)

 I'll remove it.
