Hmm, not sure what happened to the patch to frmMain.h - it looks like
a diff between 2 modified versions of the file, rather than the
original and new. I'd suggest just doing an 'svn diff' from the top
level directory in future - that will create a single patch for all
the changes.

The only crash I could get in the debugger was if I searched for
'Dummy'. The treeview often has dummy nodes attached which the user
never sees - these aren't linked to an object , so when you do this:

currentObject=browser->GetObject(item);
treee->AppendItem(treee->GetRootItem(), browser->GetItemText(item),
currentObject->GetIconId(), -1, currentObject);

you end up with currentObject == NULL which results in a crash.

From what I can see in the patch, it looks like you're testing on
Linux - I do the bulk of my debugging on Windows as the MSVC++
debugger makes it much easier. My guess is the different OS is the
reason why you see a crash and I don't, however, I suspect it's
happening because you're modifying currentObject which you should
almost certainly not be touching.
