 Is there some problem with the fsData::fsData() constructor used in
 kmountmangui.h?

 After trying the above fix, the compiler generated an error with:
 opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_kde_krusader/work/krusader-2.0.0/krusader/MountMan/kmountmangui.h:116:
 error: call of overloaded 'QString(int)' is ambiguous.

 A google search revealed other projects had similar errors when attempting
 to initialize QString with an int -
 http://bugs.scribus.net/view.php?id=8983 "Build of Scribus 1.3.6 on Fedora
 Rawhide with Qt 4.7 Technology Preview failed because there are 2 places
 where QStrings are initialized with 0 instead of QString::null and the
 compiler throws an error"and https://bugs.launchpad.net/ubuntu/+source
 /konq-plugins/+bug/600597 "Compile fixes for Qt 4.7. (Can't initialize
 QString with an int anymore)".

 In kmountmangui.h replacing

 class fsData {
 public:
    fsData() : Name( 0 ), Type( 0 ), MntPoint( 0 ), TotalBlks( 0 ),
    FreeBlks( 0 ), Mounted( false ) {}

 with

 class fsData {
 public:
    fsData() : Name(QString::null), Type(QString::null),
 MntPoint(QString::null), TotalBlks( 0 ),
    FreeBlks( 0 ), Mounted( false ) {}

 allowed a compile.

 Next compile generated an eror with:
 opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_kde_krusader/work/krusader-2.0.0/krusader/krslots.cpp:453:
 error: call of overloaded 'QString(int)' is ambiguous

 In krslots.cpp replacing

 KrSearchDialog::SearchDialog = new KrSearchDialog();

 with

 KrSearchDialog::SearchDialog = new KrSearchDialog(QString::null);

 allowed krusader to compile

 Unfortunately, I am not a programmer so these changes might do more harm
 than good.
