I'm not sure, but another crash report seems related to this:

The problem here is that in Snippet svn_wc__conflict_invoke_resolver(),
the call
if (cancel_func)
SVN_ERR(cancel_func(cancel_baton));
calls into invalid memory. The exception is actually "Access violation
*executing *code" so it seems that here too a wrong/invalid ctx is used.
(sorry for the html mail, but with text the long lines of the stack
trace just get mangled to an unreadable state)
