Houdini SGTK App crash on close

I everyone, I’m trying to use SGTK apps with Houdini 18.0.460, and each time I have an opened App (like tk-multi-workfiles2 or tk-multi-publish2) and I close Houdini, I get a crash.

My log is

Any idea on what happen here ?


Hi @tristanlg

I’m sorry you’re hitting issues, what versions of the following are you using?

  • tk-houdini
  • tk-core
  • tk-multi-workfiles2
  • tk-framework-shotgunutils
  • tk-framework-qtwidgets



Hi @tristanlg

We’ve actually reproduced the issue on our side as well, and I’ve ticketed this up.
Thanks for reporting it, we’ll post back here once it is resolved.



Hi !
Thanks for your feedbacks @philip.scadding !
We’ll wait for a fix.



Hi @philip.scadding, any news about this bug ? :slight_smile:

Hi @tristanlg,

It looks like this is still in our backlog to fix, we don’t currently have any updates for you sorry.

Looking the at the testing it seems it affects Houdini 18.0.407+, Would a current workaround to use an earlier build be an option for you?

Hi @DavidMason and @philip.scadding,

We are using Houdini 18.5.696, and we are still facing the issue.

Any news?
