KFileItem / KFileIconView bug?

[Sascha Cunz]

Hi,

in bugs.kde.org i found at least 3 bugs[1] that crash in the destructor of 
KFileIconViewItem.

This destructor is a one-liner that (from my point of view) can just crash if 
the KFileItem is destroyed before the KFileIconViewItem ( Or if the KFileItem 
was never valid, which i doubt to be the case).

Looking at a Bugzilla query for "~KFileIconViewItem" in open and closed bugs 
reveals that such behavior is there since before KDE 2.0 (Though the code 
must have been changed for KDE3.0)

How likely is it that a KFileItem is destroyed unwanted or too early?

If I'm right in that, then shouldn't it possible to use a pointer that will 
reset itself to NULL when the object it points to is deleted? Maybe we can 
introduce some safety here for KDE4?

Regards
Sascha

problem; fix seems to "avoid" problem)

Older (closed) bugs that also have backtraces showing the last known code 
position to be ~KFileIconViewItem exist.
