ubuntustudio-controls crashed with AttributeError in serialze_settings()

This crash has the same stack trace characteristics as bug #194835. However, the latter was already fixed in an earlier package version than the one in this report. This might be a regression or because the problem is in a dependent package.

I had thought I'd fixed this bug. Could you please list exactly the steps taken to reproduce this crash, from opening to closing as well as any setting you had (or had not) set.

I'll try.

I reinstall the package (I doesn't need it so I remove it). When it crashed last time I doesn't change any setting before closing and had launched ubuntustudio-controls from gnome-control-center.
Now, I started directly gnome-control-center via the terminal (sudo gnome-control-center). It prints me immediately this :
$ sudo ubuntustudio-controls
__main__
/usr/bin/ubuntustudio-controls:32: GtkWarning: Ignoring the separator setting
  self.wTree = gtk.glade.XML(self.gladefile)

(ubuntustudio-controls:18309): libglade-WARNING **: could not find a parent that handles internal children for `vbox'
Traceback (most recent call last):
  File "/usr/bin/ubuntustudio-controls", line 184, in <module>
    uscontrols.serialize_settings()
AttributeError: Uscontrols instance has no attribute 'serialize_settings'

I'm updating now my computer, I'll try again after reboot.

PS : sorry for my bad English.

[System updated]
But if I start the application from gnome-control-center (like the first time) it doesn't crash anymore. (No value change before closing.)
From the terminal it crashes.

I think this needs some debuging is real time. Would you be able to join #ubuntustudio-devel and ping rexbron so we can set up a time?

Yes I can do what you want. But I don't know what '#ubuntustudio-devel' is :·s .
Please tell me more about what I'm suppose to do.

A list of official Ubuntu IRC channels, as well as IRC clients for Ubuntu, can be found at https://help.ubuntu.com/community/InternetRelayChat . Once you have joined the freenode channel please join #ubuntustudio and ping (type my name) 'rexbron'.

Sorry, marco. Quassel has locked me out for the moment. I have fixed the second traceback you have reported. That was due to a typo in the code.

I will be testing this on my machine and will give you instructions on how to do it on your own.

No problem. ;)

Ok, I uploaded a package to the Ubuntu Studio PPA[1] that fixed the second traceback you posted. Please test it and try and replicate the bug.

With this upgrade it works fine. (excepts one warning)

$ sudo ubuntustudio-controls
__main__
/usr/bin/ubuntustudio-controls:32: GtkWarning: Ignoring the separator setting
  self.wTree = gtk.glade.XML(self.gladefile)

(ubuntustudio-controls:21646): libglade-WARNING **: could not find a parent that handles internal children for `vbox'

Thanks

Those warning are harmless. I will be pushing the fixed package to the main archives today.
