--- Comment #4 from LIGHTNING UK! lightning_uk@imgburn.com 2011-07-27 09:39:03 CDT --- Ok so I've done a bit of digging around today and I have now found the cause for this crash.
Wine doesn't seem to have any code for 'SHGetKnownFolderIDList'.
It's a new function that was first available in Windows Vista.
The 'TVirtualExplorerTree' component wants (and expects to be able) to use it on Vista+ OS's but GetProcAddress(Shell32DLL, "SHGetKnownFolderIDList") just returns null.
Without it, lots of things end up being invalid (null/nil) pointers and that's what causes the crash.
