First observations:
Package does build cleanly on FC5 devel

However filepermissions for the %doc files are 755, they should be 644. This
makes  rpmlint complain:
rpmlint  /usr/src/redhat/RPMS/i386/wp_tray-0.4.6-1.i386.rpm 
E: wp_tray script-without-shellbang /usr/share/doc/wp_tray-0.4.6/COPYING
E: wp_tray script-without-shellbang /usr/share/doc/wp_tray-0.4.6/ChangeLog
E: wp_tray script-without-shellbang /usr/share/doc/wp_tray-0.4.6/TODO

E: wp_tray script-without-shellbang /usr/share/doc/wp_tray-0.4.6/AUTHORS
E: wp_tray script-without-shellbang /usr/share/doc/wp_tray-0.4.6/NEWS

The icons for displaying in the gnome menu seem to be missing, though the
desktop file has:
Icon=/usr/share/pixmaps/wp_tray/

There's no such directory / files in the build package.

The configuration dialog seems to be nothing but a glade template with no
functional code, none of the buttons do anything, only way to close it is by
clicking the [X] window icon

The 'wallpaper search too' seems to be just as function-less as the config dialog.

The URL to the home page gives a 404, should probably read:
http://planetearthworm.com/projects/wp_tray/index.php

The Source0: tag should really use atleast %{version}, so it auto updates with
version updates. Also the download link is (now) invalid, the line should read
something like:
Source0: http://planetearthworm.com/projects/wp_tray/files/%{name}-%{version}.tar.gz

Much newer upstream version is available (0.5.1), might be worth updating? It
seems to address the non-working dialogs among other things.

New upstream version does have a lot of new/different requirements. I think to
satisfy its new requirements you'd probably need:
BuildRequires:  libglademm24-devel libgnomecanvasmm26-devel gconfmm26-devel
libgnomemm26-devel libgnomeuimm26-devel          
Requires:       libglademm24 libgnomecanvasmm26 gconfmm26 libgnomemm26
libgnomeuimm26          

Which are present in atleast fedora-extras-development (haven't checked for FC4,
but should be)

What else you'd need is the boostfilesystem libraries, which unfortunatly are
not packaged for Fedora Extra's yet (though feel free to :-)) which i think are
located at: http://www.boost.org/

If you make your way thru all of that i'd be happy to give a formal review

Proposed 0.5.1 specfile

Changed the original spec around to the upstream 0.5.1 version, removed desktop
file handing (no longer there) and added gconf handling, plus all the new *mm
and boost dependencies

Still awaiting responce from Ignacio, hope your not lost in bugzilla spam and
forgot about this? :-)

JFC, you'd think I have nothing to do all day but pop out packages for Extras :P

Updated.

Thanks update looks good.

Formal check list:

MUST review items:
- Builds cleanly on FC5 devel.
- rpmlint:
W: wp_tray non-standard-dir-in-usr libexec
(ignorable error, its the standard location for applets)
- Source included matches upsteam source (md5sum)
- Package name meets guidelines
- spec file name is in %{name}.spec format
- Licence (GPL) is fedora extra's compatible & is included
- Spec file is in (american) english
- Does not list BuildRequires that are excepted in the package guidelines
- All build dependencies are listed
- No ldconfig needed
- All files have proper permissions
- Package is not relocatable
- No duplicate files in %files section
- No missing files in %files section
- Has a proper %clean section with rm -rf $RPM_BUILD_ROOT
- Uses macro's described in PackagingGuidelines
- No entries in %doc that are required for standard program operation

Should items:

Thanks for the updates, FE-APPROVED

I remeber seeing import logs for this, did you make tag && make build? Bug is
still waiting for being closed as "NEXTRELEASE" for when it is :-)

Built under FC4 and devel.
