[Message part 1 (text/plain, inline)]

I tried to report the bug within emacs, but somehow I couldn't because of some issues with email client setup (I am very new to emacs). So I am using email directly instead. The following text, I copy and paste from my writing in emacs bug report file that I failed to send within emacs:
I installed 24.5 in windows 7. Everything worked perfectly (after installing sbcl, quicklisp, slime etc). The issue is after I did the following: 
I downloaded gtk3.6.4 all-in-one bundle fromhttp://www.gtk.org/download/win32.php, unzip it and put the path,/dir-to-gtk-bin/, in the windows environment variable, as instructed. The moment I put the pathin, emacs hang during the starting process. The menu appears but I can'tclick it. I have to alt-contrl-del to kill it. Emacs starts normallyafter I removed the path. I have read the FAQ  for emacs and emacs inwindows. It looks like that emacs will use GTK images if the path isin. I think that there is some conflict with the newest image lib in thegtk3 under windows, since most of the lib versions in the gtk/bin isnewer than those in ezwinports.  But I am too noob to check whichone. Thanks.

You are in DLL hell.  To fix that, copy the libraries you downloaded
from the ezwinports site to the same directory where you have
emacs.exe.  Then Emacs will use the ezwinports libraries and not those
from GTK.

Bravo, Eli!!! Thanks a lot. I don't know what a "DLL hell" is, but it works! I downloaded librsvg and all its required libs and installed them. And now emacs can start normally. I think one should put a link in FAQ about using gtk3 in emacs under windows: One has to use the port from ezwinports first before using gtk3+. Your help is greatly appreciated. How do I close the bug report now? Andy,

It's a situation where you have several incompatible DLLs of the same
name that fight each other, and give you hell.

We already advise to prefer ezwinports to GTK ports (see README.W32).  I
actually don't understand why you tried to install them, and why you
think the GTK ports are newer: none of the libraries they distribute
have newer versions than what you have on ezwinports.

Send email to NNNN-done <at> debbugs.gnu.org, where NNNN is the bug
number.  I did that for this bug.

Thanks.
