Perl file exists test fails when path contains spaces

Below is an example of what I am talking about

$PathPlusFileName gets set in Gtk2 File Chooser dialog SUB

if (-e $PathPlusFileName) {
    print "found file\n";
} else {
    print "did not find file\n";
}

IF block works as long as there are no spaces in the PATH name. Did try double quoting the path, didn't help. Any suggestions on how to correct would be appreciated.
