Trailing message box that can't be closed after sync

[Kienan]

Mnemosyne: 2.4 (downloaded from the the project website) running Debian Sid (most packages from regular sources, python3-pyqt5 from pip since QtWebEngine isn't packaged in debian)

After I run a sync, there's a dialog that has a small bit of text and can't seemingly be closed. See attached screenshot (it starts small, I had dragged it out to see if I could see more of the text there). The dialog can be moved out of the way, or alt-tabbed around - it's not blocking any operation.

 ~/.local/share/mnemosyne/log.txt doesn't seem to contain any information other than repetition information and database saves. This is the output of when run from terminal :

Can you try with the latest PyQt5 installed through pip3 and see if that makes a difference?

[Peter Bienstman (peter-bienstman)]

Closing due to lack of feedback

[Kienan (viashimo)]

Still see it: mnemosyne 2.4.1, pyqt5 (5.7.1 from pip3),

[Peter Bienstman (peter-bienstman)]

Just to be sure: this dialog box that remains open is on the sync client, right?

[Kienan (viashimo)]

Yup. The server synced to is running headless.

[Peter Bienstman (peter-bienstman)]

I've made a new version which sends out an extra 'close progress' signal just to be on the safe side.

You can find it here: https://www.dropbox.com/s/84e6hbde1idfsvn/Mnemosyne-2.4.1-sync-progress-bar.tar.gz?dl=0

It will also print out some extra debug statements. In my case, this is the output:

Warning: Could not import OpenGL. Might cause a black screen on some Linux distributions. Try installing python3-opengl in that case.

[Kienan (viashimo)]

Tried the build from the the dropbox dl, no change for me. Do you get the

QIODevice::write (QProcess): device not open
b'Waiting for uploader thread to stop...'
b'Done!'

before you close mnemosyne? I see the debug code.

Here's the output up to the end of the sync, but before mnemosyne is closed.

Your debug output looks perfectly OK: all the necessary calls to close the progress bars are being executed. So, it must be a Qt specific problem on your installation. Perhaps you can try with upgrading to PyQt 5.8, but I'm afraid there's nothing more I can do about this on my end...
