           Summary: systemsettings SIGSEGV setting desktop path to
                    /home/user
           Product: systemsettings
           Version: unspecified
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: schatzb at gmail.com


Version:           4.1.3 (using KDE 4.1.3)
Compiler:           Whetever Debian KDE team uses
OS:                Linux
Installed from:    Debian testing/unstable Packages

Using Debian Experimental KDE4 packages (4.1.3) on Lenny, kernel 2.6.26.

Since the folderview plasmoid, I deleted ~/Desktop. I then tried to point my
desktop path to /home/user instead of /home/user/Desktop via
Systemsettings->About Me->Paths. after clicking 'Apply' it prompted me to move
the contents of ~/Desktop to the new Desktop path. The dialog silently failed
(probably because ~/Desktop doesn't exist) and 'Apply' re-enabled. On closing,
I got this stack trace:

Application: System Settings (systemsettings), signal SIGSEGV
