Crash in 32-bit shell extension on Windows x64

I have debugged an application crash that seems to be caused by TortoiseSVN's 32-bit shell extension. Here are the details:

Steps to reproduce:

1. Make sure TortoiseSVN is installed.
2. Download SonED2 from this page: http://stealth.hapisan.com/SonED/ (click "Download SonED2"). Extract the contents from the archive in some folder.
3. Start SonED2.exe.
4. Click File > Open Project.

Expected results:
An open file common dialog opens.

Actual results:
The application crashes; either Windows Error Reporting starts ("The application has stopped working") or the application terminates without any messages.

System information:
OS: Windows 7 x64 SP1
SonED2 version: v11.05.19
TortoiseSVN version: TortoiseSVN 1.7.99, Build 24240 - 64 Bit -dev, 2013/05/28 02:21:04

Other information:
I ran SonED2 in WinDbg to see if I could figure out why the application crashes. WinDbg signals an access violation (exception C0000005) in crshhndl.dll:

crshhndl!InitCrashHandler+0x4d2:
095c2282 ff15a0fe0000 call dword ptr ds:[0FEA0h] ds:002b:0000fea0=????????

By the way, there is no symbol file for crshhndl.dll in debugsymbols64.zip...

I know of at least one other person with the same issue on Windows 8 x64.

I can work around the issue by renaming the 32-bit shell extension DLLs so that they are not loaded by the open file dialog in SonED2.
