drawable is not a pixmap or window after upgrade to 2.8.9

[Eduardo M KALINOWSKI <ekalin bol com br>]

    I recently upgraded from GTK version 2.6.something to 2.8.9 in my
Debian system. Now, when running an application I developed myself, I
get a bunch of errors like this:

Gdk-WARNING **: gdkdrawable-x11.c:904 drawable is not a pixmap or window

    They happen when I press any key in a GtkEntry. The program works
normally, though.

    I've generated a stack trace from the call to g_log:

I'm not sure that's useful, but I've found out that the error only
starts to appear after I call gtk_entry_set_visibility to hide the text
in the Entry, and later call it again to make it visible once more. If I
remove the calls to gtk_entry_set_visibility, the error never appears.

I'm using GTK+ version 2.8.9, glib version 2.8.4 and cairo 1.0.2.

Why are you so hard to ignore?
