Well, if that were really true, then almost every application would
crash if TSVN was installed!

Please post the part of your code where you initialize and show the file
open dialog.

Sure, but where's the stacktrace?

Well, it's definitely not a Tortoise bug. Think about it: your app is
not the only one using file open dialogs. Almost *every* application
does that. If TortoiseSVN really would have such a bug, they all would
crash too and that bug would have been found centuries ago.

Oh, and you didn't mention which version of TSVN you've got installed.

Please make sure that you initialize *all* necessary fields in the
OPENFILENAME structure. Maybe your app has a bug which only shows if
shell extensions show some overlays...
