My system:
Debian Squeeze, with Gnome 2.30.2
Vanilla Revelation, installed by distro
To reproduce:
I went to Amazon and copied the "sign in" url. Then opened the "add new entry" dialog in Revelation, changed the type to "Website", and pasted in the url, and saved the entry. As soon as Revelation redraws the window with the new entry highlighted, it resizes the window. The pane on the right, which shows the url, is now very wide, and the pane on the left gets sized similarly. The result is much wider than my 1280-pixel-wide monitor.
The url that causes the problem for me is:
https://www.amazon.com/ap/signin?_encoding=UTF8&openid.assoc_handle=usflex&openid.return_to=https://www.amazon.com/gp/yourstore%3Fie%3DUTF8%26ref_%3Dpd_irl_gw%26signIn%3D1&openid.mode=checkid_setup&openid.ns=http://specs.openid.net/auth/2.0&openid.claimed_id=http://specs.openid.net/auth/2.0/identifier_select&openid.pape.max_auth_age=900&openid.ns.pape=http://specs.openid.net/extensions/pape/1.0&openid.identity=http://specs.openid.net/auth/2.0/identifier_select
