OS:          Linux

Open konqueror and press F9 to bring up the Navigation panel

Select the Network view.  Two folders are shown, "FTP Archives"
and "Web sites".  Right click on the former, and select
"Open in new window".  A new konqueror window appears, browsing
a directory something like
file:/home/rparlett/.kde/share/apps/konqsidebartng/virtual_folders/remote/ftp/

In the right-hand directory view of the new window, right click
and select "Create new"->"Link to location(URL)"

A modal dialog appears.  Enter "test" into the name field and
"ftp://ftp.kde.org" into the URL field.  Click okay.

Now go back to the original window, expand the "FTP Archives" node
to show the new "test" entry.  Expand it by right clicking on the +
and konqueror will crash.

To show what is causing this, firstly repeat the first two steps above.
Then right click on the entry "test.desktop" and select "Properties".

In the properties window, select the URL tab.  Change the URL from
ftp://ftp.kde.org
to
ftp://ftp.kde.org/

Click okay.  Now the node will expand and work correctly.



Stack trace follows.
