don't use wxFileConfig to parse kdeglobals, it's not meant for such use. Fixes bug 939195

+    // FIXME: This code is heavily broken. There are three bugs in it:
+    //        1) it uses only KDEDIR, which is deprecated, instead of using
+    //           list of paths from KDEDIRS and using KDEDIR only if KDEDIRS
+    //           is not set
+    //        2) it doesn't look into ~/.kde/share/config/kdeglobals where
+    //           user's settings are stored and thus *ignores* user's settings
+    //           instead of respecting them
+    //        3) it "tries to guess KDEDIR" and "tries a few likely theme
+    //           names", both of which is completely arbitrary; instead, the
+    //           code should give up if KDEDIR(S) is not set and/or the icon
+    //           theme cannot be determined, because it means that the user is
+    //           not using KDE (and thus is not interested in KDE icons anyway)
+
