Description Jeffrey Goh 2020-10-29 13:58:23 UTC 
Description of problem:

deepin-dock (aka dde-dock in /var/log/messages) crashes on startup. 


Version-Release number of selected component (if applicable):

5.0.0.4.fc33


How reproducible:

Always


Steps to Reproduce:
1. Login after selecting Deepin as Desktop Environment 
2. dock appears, then disappears
3. open Terminal - run dde-dock in command line

Actual results:

$ dde-dock 
"dtkwidget" can not find qm files
"dde-dock" can not find qm files
Attribute Qt::AA_EnableHighDpiScaling must be set before QCoreApplication is created.

Expected results:

Dock should appear on screen and stay on screen

Comment 1 Robin Lee 2020-10-30 10:31:41 UTC 
Do you have dnfdragora-updater installed? Remove it and reboot the system to see whether the issue persists.
Comment 2 Jeffrey Goh 2020-10-30 14:35:54 UTC 
As unintuitive as that was, removing dnfdragora-updater made deepin-dock work, so that seems to be a valid workaround (I don't use dnfdragora-updater anyways) - but I would like to know the root cause, if you care to explain?
Comment 3 Robin Lee 2020-10-31 03:57:33 UTC

We still need further investigation. Currently I found the issue occurs if dnfdragora-updater and python3-pystray(>=0.17, with new requirements) are installed.
