I cannot reproduce this on my computer. And this time the backtrace tells what is broken in the worksheet but not when it broke. But I hope it will be fixed in the next maxima release.
The .deb packages from https://code.launchpad.net/~peterpall/+archive/ubuntu/wxmaxima-nightlies should be installable on debian-testing. Would it be possible for you to test them? As soon as we manage to resolve the last problems with building .apk files for the mac platforms there will be a new release I am planning to upload to debian-testing again. Kind regards, Gunter.
