Reproducible: Always

Steps to Reproduce:
Attempt to view ftp.kde.org, or any other FTP site, in Konqueror.

Actual Results:  
Crash as above


Expected Results:  
No crash, directory listing should be displayed


This seems to be a consequence of commit 014e8f3c to kdelibs/kioslave/ftp/ftp.cpp.  Reverting this commit fixes the problem.

Restoring the deleted 'entry.clear()' at line 1559 alone also fixes the problem, at least for the test cases that I have tried.
