not really.

it's usually possible to fix a deadlock from just a backtrace of all
threads.

you say you have a user who has been blessed by the gods with an ability
to reproduce the problem, so give them an LO with debug symbols (perhaps
use Kendy's fancy symbol-server thing or build it yourself), and once
it's properly locked up attach Visual Studio (or windbg) and copy all
the stacks and file a bug (CC: me).
