editing locations to the clock applet, keyboard navigation closes the dialog unexpectedly

[Oren_B]

Binary package hint: gnome-panel

When I edit the locations in the clock applet preferences and I navigate the dialog with the keyboard, pressing Enter on any button causes the dialog to close, as if I pressed the Close button. The Close button actually stays highlighted all the time, even when I highlight a different button. If I activate a highlighted button using the space bar instead of the Enter key, it works as expected.
This bug is very similar to a bug I filed against update-manager a few months ago:
https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/422673
Maybe they are both caused by the same underlying bug?

Thanks for the report, may you take an screenshot of that dialog and attach it to the report? Thanks in advance.

Screenshot attached.

Thanks Oren, could you attach gdb to that process ? the name should be something like /usr/lib/gnome-panel/gnome-clock-applet-mechanism ; for instructions on how to use gdb please read http://wiki.ubuntu.com/DebuggingProgramCrash ; thanks in advance.

First I have to say that I get the impression that the program doesn't really crash, but simply closes due to some error in the default action linked to pressing the Enter key.

I tried to follow the instructions and didn't really succeed. I'm not sure I was doing it correctly. Here's what I did, maybe you can find what I did wrong:
Installed the gnome-panel-dbgsym package, navigated to
/usr/lib/gnome-panel/
and from that location I ran gdb. Here's the outpou of the first try:

So I tried the same thing with sudo, but that didn't seem to work either:

[Sebastien Bacher (seb128)]

the issue seems to be the default action binded to enter use

[Oren_B (oren.barnea)]

The current theme in Maverick shows that indeed there is some ambiguity regarding the selected button when navigating this dialog using the keyboard: the Close button is constantly highlighted in bright orange color on it all the time, and stays highlighted when the Tab key is pressed. Other buttons get highlighted with an orange frame around them, that moves from one button to the next upon pressing Tab. The bright orange button face seems to be associated to pressing Enter, and the orange frame seems to be associated to pressing Space Bar.
