New GTK+2.0_2.23.3-1ubuntu2 breaks certain gnome-panels applets

[Harry]

After todays upgrade of GTK+2.0_2.23.3-1ubuntu2 certain applets are broken, at least they are invisible in the panel.
These applets are certainly affected:
- Clock (including Weather and Calendar functions)
- Wastebasket (Trash)
- Notification Area (including Network-Manager-Applet)
I am experiencing this with the Gnome-Classic DE.

As a workaround, applets do reappear, when I downgrade to the previous version of GTK (2.23.2-0ubuntu4).
Installing the version 2.23.3-1ubuntu2 I get the following error message:

Unpacking replacement libgtk2.0-bin ...
Processing triggers for man-db ...

Same bug also affects Flash within Firefox and Chronium. Flash video fails to appear in the Firefox browser window with the following messages appearing in the terminal:

(<unknown>:3369): Gdk-CRITICAL **: IA__gdk_window_get_origin: assertion `GDK_IS_WINDOW (window)' failed

(<unknown>:3369): Gdk-WARNING **: /build/buildd/gtk+2.0-2.23.3/gdk/x11/gdkdrawable-x11.c:952 drawable is not a pixmap or window

Chronium will tell you that the Flash plugin has crashed.

Downgrading GTK+2.0 package to version 2.23.2-0ubuntu4 will allow Flash to work again.

I am afraid this is not fixed yet.
The panels are OK and appletts working, but there is another issue with this GTK+2.0_2.23.3-1ubuntu3 now.

Firefox, Thunderbird and Chromium all crash immediately if you mark (paint) text and select (right-click on mouse) copy.

[Harry (harry33)]

I get "segmentation fault" in terminal:
chromium-browser
Segmentation fault

[Harry (harry33)]

And as before,downgrading to the version GTK+2.0_2.23.2-0ubuntu4 works OK, no more segfaults.

Thanks for the testing Harry, I have uploaded 2.23.3.is.2.23.2-0ubuntu1 which should roll back to the previous version. I'm running it locally and it doesn't have any of your reported problems.

Just as a counterpoint - in 2 machines the upgrade to package gtk+2.0 - 2.23.3-1ubuntu3 has had no ill effect at all, at least as mentioned here.
All this points to is the tremendous in inconsistency atm in natty which seems to make telling whether an update or upgrade is any good very difficult. (have seen similar on some other recent bugs.

[Harry (harry33)]

I can confirm the roll back version works just fine.
So this is fixed for now.
Thanks Robert.
