Thanks, seems to work fine for me (no crash while browsing about 50 
directories).

I had a short discussion with Alexandre on IRC yesterday. He says that the 
basic problem is probably the passing around of the infoPtr to represent the 
listview instead of the handle. As far as I understood, we should probably 
change all functions to take a HWND instead of a LISTVIEW_INFO* parameter. We 
should then try to retrieve infoPtr via GetWindowLongPtrW as soon as we need 
it. And we should be aware that infoPtr might point to a free'd location 
after every SendMessage.

I've attached another patch, which fixes the crash in the file dialog applying 
this scheme. I've only changed as much as necessary to fix the problem, 
though. 

Bye,
