I’m the new wimp of the day, as I accidently uploaded the wrong installer binary for 4.2.1.1 (I uploaded 4.2.1 with the panel bug again). I updated the mirrors now (except for www.us.xfce.org, www.xfce.org redirects to this mirror so don’t download from xfce.org now, which will be updated during the next 3-4 hours) with the correct 4.2.1.1 binary, and everybody who installed 4.2.1.1 from the installer should refetch the binary and reinstall. Sorry for the inconvenience caused by this doomed 4.2.1(.1) releases.
Update
Brian’s comment on this was:
<kelnos> we need a new motto
<kelnos> Xfce: Our software rocks, but we can't release it for shit
Since 4.2.1 contained this critical panel bug, we did a quick 4.2.1.1 release yesterday, which fixes the panel issue. All users of Xfce 4.2.1 should upgrade to 4.2.1.1. Updated installers are available from Xfce installers website.
So I added the firefox-like location bar to Thunar today (Brian Schott came up with that idea yesterday) and after playing around with it for some time, I’m pretty sure that this is the solution to the location bar problem we’ve been trying to find during the last weeks.
It’s just great, you can navigate using the keyboard, but the location entry widget isn’t visible until you need it. This is great for newbies and power users, as it combines the best of both worlds: Newbies will use the path bar and the shortcuts for mostly everything, while power users can easily enter paths if necessary.
Brian Schott came up with a new - actually borrowed from ROX - idea for an Open Location control in the GtkFileChooser-like UI:

Here we’d have a fast and easy way to jump to a different location wihout the need to popup a separate dialog.
My original attempt (and that’s how it’s currently implemented in the prototype) was to have a separate Open Location dialog:

See the thread on the mailinglist for the discussion concerning these ideas.
Funny, right after the 4.2.1 release is finally done - well, except for Olivier’s ChangeLog
/NEWS
- somebody files a critical bugreport against xfce4-session 4.2.0: xfce4-session - the simple and balou engines to be exact - crashes on startup with new freetype2 2.1.10cvs (well, not surprising that mice doesn’t crash, as it doesn’t render any text). Looks like a 4.2.2 release is not far away…
