Thanks Frank,

mine is definitely Bug 23576

Hey all,
thanks for all the feedback, we've been following your comments carefully and apologise if it's been causing you any problems.
We're not aware of any crash-on-exit bugs after using large amounts of memory i.e. after rendering large, complex scripts. Does anyone have any concrete reproducible steps? If so we will log a bug and investigate. We did have some issues with Quicktimes in Nuke 9.0v4 and earlier which would have been exacerbated by rendering large files.
We fixed one NukePanels crash-on-exit in the latest release, Nuke 9.0v6 so it would be great if those of you who use nukescripts.panels could see if that helps your issues: 

    Bug 47788 - nukescripts.panels crash [RESOLVED - 9.0v6+]
On a related note, we also have some long-standing bugs with PySide, such as the one Ben Dickson mentioned. We suspect that this is we're on quite an old version of PySide and it looks like the PySide guys have fixed a couple of crash-on-exit fixes in releases later than the one Nuke uses (Nuke is on PySide v1.0.9 - as of Nuke 8.0, which correlates with Mr Rueter's comments). Right now, the best we can do is recommend that you keep any PySide code simple, but we will try to look into it further: 

    Bug 23576 - Segmentation Fault on Nuke exit after using a custom
    PySide window [REOPENED]
We are also aware of issues with custom workspaces which we are looking into as I type.
> "QClipboard :: event(class QEvent *) Cowardly refusing to send clipboard message to 
> hung application"
This message relates to Quicktime Helpers, an issue we fixed for 9.0v1. I'm not sure if we back-ported it to 8.0v7.
We were not aware that so many of you were getting native-OS crash reports (instead of Nuke's custom handler). This means that we don't see those reports which means we don't fix them, so I've logged a bug for us to try and make sure we handle more cases where Nuke (unfortunately) crashes. 

    Bug 49364 - [Crash Reporter] - Being unloaded before
    application-teardown completed
We'll try and look into most of these issues a bit more, so thanks for letting us know.

    We have custom nuke panels (PySide) which are required to save a
    comp (so they are pretty much always loaded) but the crashes on
    exit does not always happen. So I wouldn't make the assumption;
    custom nuke panels == crash.

    There's probably more to it.

            Click HI, then close the window and Nuke and I get a

            In Nuke 8.0v6 everything used to work fine.  What are
            the versions of Qt or PyQt that should be used?
            My query reports:

            ('Qt version:', '4.8.4')

            ('PyQt version:', '4.10.2')

                I get it every time the moment I use the viewer.
                -start nuke
                -create checkerboard
                -hook up checkerboard to viewer
                -close nuke
                -seg fault

                Without my pipeline code (which does register a
                couple of PySide widgets as nuke panels) it doesn't
                happen, but it never used to happen before Nuke 8.

                Reported this back when it started in Nuke 8
