Package: libgtk2.0-0
Version: 2.6.10-1
Severity: important
When running Freeciv 2.0 (currently in debian unstable, also downloadable
from http://freeciv.org/) under valgrind, I get a number of warnings and
errors inside the glib and gdk libraries. Some of these are actual errors
that look like they could cause a crash under the right circumstances.
The natural tendancy is probably to blame the calling code for these
errors rather than the library, but I don't see how this could be the case
here. In fact several of the major bugs (an invalid read inside
gtk_parse_args) can be reproduced using the program below. Other bugs aren't
included here but the full output of the valgrind runs can be found at
Valgrind run on bug.c:

If this is useful in tracking down the bugs, I'm happy to provide further
test programs that will show the other errors I come across.
