[Freeciv-Dev] (PR#10246) Segfault(s) in GTK

["Marek \"Baczek\" Baczyński" <imbaczek@xxxxxxxxx>]

<URL: http://rt.freeciv.org/Ticket/Display.html?id=10246 >

So I managed to crash Freeciv again, this time in the GTK department.
(And that's still the  same game I started a few hours ago :)) I have
absolutely no idea what caused it -- it happened after some kind of
interaction from my side, but don't remember what exactly. Coredump
availible on request. Savegame from some turns earlier attached.

I also have another mysterious segfault happening, but am not sure if
it isn't actually an OOM killer (even though I have 300 MB of unused
swap.) This happened during selecting a goto destination.

Previous frame inner to this frame (corrupt stack?)

Should I forward these reports to GTK/glib maintainers?
