net-irc/xchat-1.9.3-r2 installs an erroneous .desktop file.
Although the binary is named "xchat-2" the .desktop file
contains "Exec=xchat". Thus when started from the GNOME
menue the non existant binary "xchat" is started.
Substitution "Exec=xchat" with "Exec=xchat-2" in
/share/applnk/Internet/xchat.desktop fixes this.
I know, its a masked devel version. Anyway, i don't know if this is a good
solution, since xchat1 writes the same file. So if you had them both installed,
you wouldn't have 2 menuitems.
Had a fix locally for the first problem, but there are some other problems with
this ebuild as well, which i want to fix in time.
