Cannot reproduce, I'll get message box which says that / is illegal in folder name.

I have reproduced it on 2 machines and a collegue has reproduced it on their machine. The two machines I have tried it on are a 64bit Linux machine and a DELL workstation. My collegue has reproduced it on a DELL laptop.

The / has to be part of the mail subfolder name, e.g. "dsfsdf/dsgfdsgs" will cause KMail (incl. Kontact) to produce several error windows followed by a crash.

This is still a problem with KMail 1.9.1 on KDE 3.5.2.

If you use the "maildir" format mail folders, go to create a new subfolder. Enter the folder name as "crash/me" (without the quotes) then go through the error windows and watch KMail crash and burn.

The problem is that KMail is not escaping the "/" character from the text that the user entered.

Trying to reproduce this I found that while creating a folder '/' as a subfolder of a toplevel folder results in an error message that this is not possible, creating a such folder in other subfolders is possible and lead to the following error message

>Fehler beim Öffnen von /home/carsten/Mail/.OS >Development.directory/.Bugzilla.directory///new. Dieser Ordner ist nicht >vorhanden.

or in english

Error when opening /...  
Dev... This folder does not exist.


After clicking the message away multiple times, the folder shows up in the tree and the io slave crashes with 

kio (KIOJob): error 11 /usr/kde/3.5/share/apps/kmail/about/box-center-kmail.png
kmail: updateSearch( -- )
kmail: updateSearch( -- )
*** KMail got signal 11 (Crashing)
KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = kmail path = <unknown> pid = 12546

I confirm this defect still exists, here on Mandriva Cooker & KMail 1.9.1.
Please change the status of this report from UNCONFIRMED to NEW.

This issue also exists in SuSE 10.1 with the KDE 3.5.3 packages. Please ,ark this as NEW rather than unconfirmed.
