alacarte crashed with ImportError in /usr/share/alacarte/Alacarte/util.py : cannot import name GError

[dino99]

Get that crash after right clicking on Applications menu on RR i386 logged as gnome-classic.
As apport also fail to report and apport-cli is also broken, i send the crash file below.

[Francois Thirioux (fthx)]

I simply removed the line with

from gi._glib import GError

in the file :

/usr/share/alacarte/Alacarte/util.py

I do not know if it is a dirty workaround, but it does succeed to start alacarte...

[Francois Thirioux (fthx)]

I meant :
removed with inserting a # before the bad line...

[Martin Pitt (pitti)]

Indeed, accessing PyGObject internals through gi._glib is wrong, and does not work any more with pygobject 3.7. Instead, please use the official API:

  from gi.repository.GLib import GError

or drop the line completely if it isn't being used anywhere.

[Burak Göksoy (rbgoksoy)]

6. method; to remove failure lines is worked.

me too :

 File "/usr/bin/alacarte", line 23, in <module>
    from Alacarte.MainWindow import MainWindow
  File "/usr/share/alacarte/Alacarte/MainWindow.py", line 32, in <module>

    from gi._glib import GError
ImportError: cannot import name GError

[ek0892 (kranich)]

for fix / resolv , this is my solution :

in the terminal :

sudo sed -i -e '/from gi._glib/ s/^from */### from/' /usr/share/alacarte/Alacarte/util.py

[dino99 (9d9)]

Thanks kranich,

after having executed to #11 command, alacarte stop crashing and can be used normally.
