[Bug-gnubg] import mat bug

Version: 1.1324 030831  on Windows XP

If I  import a corrupt  .mat file gnubg  crashes (both GUI  and no-gui).
This  may  seems  trivial  but  I'm running  batch  scripts  to  process
thousands of .mat files which occasionally are corrupt and would like to
recover gracefully from it.

> import mat bug.mat
