Application: rekonq (0.3.30)
KDE Platform Version: 4.3.90 (KDE 4.3.90 (KDE 4.4 RC1)) (Compiled from sources)
Qt Version: 4.6.0
Operating System: Linux 2.6.33-rc4-00081-g61c39bb x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
rekonq crashed when I tried to access non-anonymous ftp site, e.g. ftp://example.com/ after I entered a valid username/password pair.

I don't khow whether rekonq is supposed to handle FTP protocol but it certainly should not crash. ;-)

The crash can be reproduced every time.

 -- Backtrace:
Application: rekonq (kdeinit4), signal: Segmentation fault
