- Dialog will segfault if the text strings are not the right length, or too long. This is a dialog bug.

- With Zenity there is a GTK bug which writes GTK error messages in the MaxMenu configuration files.
If you encounter this bug you can fix it by renaming or removing the ~/.gconf/desktop folder.
Your desktop settings (wallpaper, theme) will be lost then, and you will have to reconfigure.

- In Linux Mint Debian Edition the GTK3 themes are not always working with Zenity.

- There is a bug in GTK3 in Zenity 3.0.0. The text field in text windows and tailboxes will not
resize it's height. The info screens will not correctly scale height also.

Zenity 3.0.0 is currently (Nov 2011) in Debian Testing. If you have Zenity 3.0.0 on
your system you can upgrade by downloading Zenity 3.2.0 and installing it with gdebi.

Get the Packages for Debian Testing or Linux Mint Debian Edition at:

http://packages.debian.org/testing/zenity
http://packages.debian.org/testing/zenity-common

Install example: sudo dpkg -i --force-all ~/Downloads/zenity*

- NOTE: During the current transition from GTK2 to GTK3 more bugs in Zenity can be expected.
