[kde-solaris] Crash in kmail (kdepim-3.1.93)

[James F.Hranicky]

Platform: Solaris 8
Compiler: gcc/g++ 3.3.2 -g (debug enabled for qt and kde)
IMAP Server: courier 1.6.2/freebsd

When running kmail, I can read some of my folders without any problems,
but when I go to read my INBOX, and kmail is retrieving the header list,
I get a sefgault (shortened gdb output):

  Program received signal SIGSEGV, Segmentation fault.

  ----:**-F1  *gud-kmail*       (Debugger:run)--L235--Bot-----------------------------------
 
  QListView * QListViewItem::listView() const 
  {
      const QListViewItem* c = this;
  =>  while ( c && !c->is_root )
          c = c->parentItem;
      if ( !c )
          return 0;
      return ((QListViewPrivate::Root*)c)->theListView();
  }

Other times, c is a different invalid value:

  [Switching to Thread 1 (LWP 1)]
  0xfbc1d34c in _poll () from /usr/lib/libc.so.1
  (gdb) c
  Continuing.

  Program received signal SIGSEGV, Segmentation fault.
  0xfc9535cc in QListViewItem::listView() const (this=0x570da8)
    at widgets/qlistview.cpp:3815
  (gdb) p this
  $1 = (const QListViewItem * const) 0x570da8
  (gdb) p c
  $2 = (const QListViewItem *) 0x149
  (gdb) 

The cast seems to have problems, I guess due to a pointer bug somewhere.
Anyone have any suggestions?
