Bug#930417: freeorion: Crash on save/load button

[Bernhard Übelacker]

Dear Maintainer,
unfortunately I got the impression that upstream bugs [1] and [2]
would really have been the same and therefore assumed the patch
[2] would actually fix this bug too.
Actually I guess just [1] is the right one - based on the
linked retrace.fedoraproject.org backtrace.

However, on a second look, I found there got another "xml" patch
applied upstream that matches even better [3].

This time I rebuilt 0.4.8-1 with the patch in [3] applied and
could not reproduce the crash when saving/loading.
In this short test I received no crash that would need
my previous proposed upstream patch, so I am not sure
if that should stay or be dropped.

Kind regards,
Bernhard
