Icons are not visible. using Ubuntu 12.04 (precise),Xphos with 3.1.5-webkit,Screen shot attached.
was never addressed while 3.1.5 was current. 3.1.6 is out, but we are waiting for a package maintainer to step up for ubuntu (fedora packages were released some time ago). if this continues to be a problem in 3.1.6, i will re-issue a similar bug report myself. in its own right, the build correctly installs relevant icons and looks normal.
if you run recent ubuntu amd64 and wish to run 3.1.6 now, there is an interim tarball solution: https://sourceforge.net/p/gnomesword/mailman/message/31979475/
