EMET does not provide any information about what exactly it doesn't
like. Attaching a debugger doesn't help either: there's no stacktrace or
any other info about where exactly in the code EMET thinks something bad
happens.
Even when I use a debug build of TSVN, I do not get any info that I
could use.

The only workaround I have:
Settings dialog->icon overlays->
"Show overlays and context menu only in explorer"

Check that box and EMET is happy again.
