The second fix got it past the call to printtree(). Then it crashed when
calling another function, printcols(), which I fixed with the first fix.
This allowed it to run without crashing, but the resultant output was
obviously wrong, with what could have been a related bug.
Anyway, I think this proves that your hypothesis was correct.

You said these were mostly fixed in the 2.95.3 series. The original bug
filer is using 2.95.2. Should I still file a bug? Or has someone got a
nightly build or something that they could test it on first, in case it's
already been fixed?
