Summary: Crashes and other trouble with repeated "Connect to
network game" / "Cancel"
Project: Freeciv

_______________________________________________________
Details:
(Found while trying to verify fix for bug #21896.)
Xubuntu 12.04 amd64; start freeciv-gtk2; repeatedly "Connect to network game"
then "Cancel" (using keyboard shortcuts for speed: hold down Alt then
c[O]nnect, [C]ancel, [O], [C], ...).
Observe a variety of symptoms:
----
1. This verbose warning message from Gtk:
(freeciv-gtk2:10919): Gtk-WARNING **: Invalid text buffer iterator: either the
iterator is uninitialized, or the characters/pixbufs/widgets in the buffer
have been modified since the iterator was created.
You must use marks, character numbers, or line numbers to preserve a position
across buffer modifications.
You can apply tags and insert marks without invalidating your iterators,
but any mutation that affects 'indexable' buffer contents (contents that can
be referred to by character offset)
will invalidate all outstanding iterators
----
2. A crash like this in the metaserver thread (seen twice):
Program terminated with signal 11, Segmentation fault.
