Hi!

wip/silvertree dumps core on NetBSD-4.99.34/20071019. I wanted to
track down the cause and started it in the debugger:
...
added party at 74,58
chunk size of 786720 read, but only 506 bytes in input
terminate called after throwing an instance of 'graphics::parse3ds_error'

Program received signal SIGABRT, Aborted.

(gdb) The program is running.  Exit anyway? (y or n) y

After that, it hangs. I can't CTRL-Z or kill -9 the silvertreerpg
process. "ps -auxwww" says:

wiz     21420  0.0  2.1 2744 21548 ttyp3  I+    4:16PM  0:00.21 gdb silvertreerpg

I can kill -9 the gdb process.

Should I send a PR?
