Batch export with Waves AU Plugins crashes on OSX 10.9

[kiepmad]

Hi all,

I have a project where I'm using Waves 9.3 AU plugins.

When I batch export with the batch exporter with Waves AU-plugins in the FX-Chain, I get a crash

I'm not quite sure if the culprit is Waves or Reaper. Using the VST effects works. Also, using the same effects chain with AU-waves-effects used on tracks renders without issue.

Replicate:
New Project
add media item
select media item
open batch file converter
add... selected media item
tick use FX Chain
FX chain... Add Waves plugin
start convert
crash

Here is the crash message.
