I get the above error when running this:

using Gtk.ShortNames
import Gtk.gtk_main, Gtk.gtk_quit
RPMbindir = Pkg.dir("WinRPM","deps","usr","$(Sys.ARCH)-w64-mingw32","sys-root","mingw","bin")
ENV["PATH"]=ENV["PATH"]*";"*RPMbindir

window = @window("Hello world")
signal_connect(window, "destroy") do widget
println("Destroy")
end
showall(window)
gtk_main()

A window still opens, but it often crashes.
I've tried re-installing it, as well as running the code in the troubleshooting instructions.
With the latter I got this error:
ERROR: Package candidate for gtk3 not found
 in select at C:\Users\user.julia\v0.3\WinRPM\src\WinRPM.jl:314

what does Pkg.installed("Gtk") report? is this a 32 or 64 bit julia installation?

I believe I may have had the same issue yesterday. The 'Usage example' below fixed it for me. At least in Repl.

See https://github.com/JuliaLang/WinRPM.jl ('Usage example' to guide WinRPM in choosing a Gtk3 variant)

See issue #165 .
