Comment 8 for bug 71322

I can reproduce this in Gutsy with

  LC_ALL=en_GB.UTF-8 aspell list < /dev/null

The error does not occur with LC_ALL=C.

Here's the stack trace obtained after installing aspell-dbgsym and libaspell5-dbgsym. It would appear that acommon::DecodeUtf8::decode doesn't like in to be NULL, even when size == 0:
