Package: ffado-mixer
Version: 2.5.0-4
Severity: important
Dear Maintainer,
After installing ffado-mixer version 2.5.0-4 the app crashes on startup
with:
```
$ ffado-mixer
Traceback (most recent call last):
File "/usr/share/ffado-mixer-qt4/ffado/panelmanager.py", line 460, in

tabshape=QTabWidget.Triangular):
^^^^^^^^^^^^^^^
AttributeError: type object 'QTabWidget' has no attribute 'West'
Aborted ffado-mixer
```
This appears to be a result of the migration from qt5 to qt6, where
enums have been moved around, and the debian package includes a patch to
add compatability. Changing QTabWidget.West to
QTabWidget.TabOrientation.West resolved that error, but lead to similar
errors for QTabWidget.Triangular and more.
The app was running OK on my system prior to the upgrade, when it was
running ffado-mixer-qt4 version 2.5.0-1.
Even after fixing the following enum namespaces:
QTabWidget.West
QTabWidget.North
QTabWidget.Rounded
QLayout.SetNoConstraint
Running ffado-mixer then sat at the main window for a few seconds (with
only the log panel visible) and then crashed with the output:
```
$ ./ffado-mixer

(this is from a tree inside my home dir, copied from /usr/ and with the
path insertion removed from ./ffado-mixer:29)
At this point I figure I'm starting to get beyond the low-lying fruit
and should submit a bug report :-)

Version: 2.5.0-5
Installing the updated package and deps has resolved the issue, thanks!
I guess you were not notified about my last comment on this matter:
https://bugs.debian.org/1131856
Please check this issue again.
I did not receive the email from your update, so thank you for following
this up with me - much appreciated.
FYI, this is the console output when closing the mixer. This does not
affect usability and might be an upstream issue, but let me know if I
should raise a bug report for it.
