Bug#485061: fenix: pixbros segfaults on level completion

[Darren Salt]

Package: fenix
Version: 0.92a.dfsg1-3
Severity: serious
Tags: patch

pixbros 100% repeatably crashes with a segfault upon level completion. I've
tracked this down (with a local debuggable fenix build) to this:

  Program received signal SIGSEGV, Segmentation fault.
  [Switching to Thread 0x7fd7a105b6f0 (LWP 6775)]
  0x00007fd7a0a28cd5 in free () from /lib/libc.so.6
  (gdb) bt
  #0  0x00007fd7a0a28cd5 in free () from /lib/libc.so.6

  #4  0x0000000000405873 in main (argc=3, argv=0x7fffa91d07d8) at main.c:406

The segfault is caused by a pointer into hyperspace; the attached patch fixes
it by ensuring that the memory is initialised.

Everything bows to success, even grammar.
