Under Wine DIALOGINFO should always be non-NULL if the dialog was create
with one of Win32 dialog creations APIs. Since they all have a dialog
template somewhere along the lines then yes, it is restricted to dialogs
created using a dialog template.
Maybe some application is pretending to be a dialog and this doesn't work on
Wine due to different offsets or something. The only time where a proper
dialog can have a NULL DIALOGINFO is just after WM_NCDESTROY.
