Package: toppler
Version: 1.1.2a-3
Severity: normal
Tags: patch
If I create a tower in level editor and start testing(playing) it by pressing
"p" in level editor, and play till the
exit (goal), program crashes. It happens because NULL pointer is used.
I changed level.cc, so that "mission" ptr is checked if it is not 0 before
usage.
