Hi,

This GTK Entry example from the tutorial crashes on gtk_widget_show() on
Ubuntu Dapper:
http://www.gtk.org/tutorial/x941.html

I got this problem with GTKmm, so I tried using GTK+. Same result with
GTK+: a crash on gtk_widget_show().

Actually I'm not certain it's a GTK+ problem; please pardon me if it is
not. In case you know what is wrong, I will very much appreciate some help.

Here is the backtrace:

Regards,


N.B: seems to be a problem with scim (I'm using scim 1.4.4):

=== Bug report here:

  http://sourceforge.net/mailarchive/message.php?msg_id=17137051

=== Solution

  1) download the sources of scim-1.4.4
  2) scim-1.4.4$ ./configure --enable-ld-version-script && make
  && sudo make install
  3) Retry running the GTK Entry tutorial example: it doesn't crash
  anymore. Ok as well using the equivalent GTKmm example.

Rgds,
