From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.8.0.7) Gecko/20061011 Fedora/1.5.0.7-7.fc6 Firefox/1.5.0.7 Description of problem: I have had the panel become unresponsive on both my i386 desktop at home and my X86_64 workstation at work. The two are not configured in the same way though both access the livnia and the freshrpm repositories. Version-Release number of selected component (if applicable): kernel-2.6.18-1.2798.fc6, gnome-panel-2.16.0-4.fc6 (appears twice after rpm - q gnome-panel) How reproducible: Sometimes Steps to Reproduce: 1.Boot up 2.Leave the machine on 3. Actual Results: Eventually -- after at least 2 days -- the gnome panel hangs. Expected Results: Dropdown menues should have dropped down when the mouse cursor is over them and the left button is clicked. Additional info: No error message. I was surprosed that rpm -q gnome-panel returned gnome-panel-2.16.0-4.fc6 twice. Certainly, I haven't installed it a second time.
Happened again but when cursor was over System drop-down menu. All function lost, couldn't move cursor or change focus or anything.
so the mouse pointer doesn't move at all? Can you toggle caps lock or switch to a vt with ctrl-alt-f1?
I have what sounds like the same problem on my x86_64 system. The gnome panel seems to lock up after being open for extended periods of time (can range from a few hours to a few days). When this happens, the menus/quick launch icons disappear on me, although the rest of the session functions normally. If I bring up a terminal and 'killall gnome-panel' the panel restarts itself and then functions normally until the next lockup occurs a few hours/days later. I haven't been able to find anything useful being logged when this happens. Is there anywhere in particular I should be looking?
This is happening to me as well, with Fedora Devel. I ran an strace on gnome-panel while it's happening and it's stuck in futex. I don't know how to debug what it's waiting on; are there tools or techniques for doing that? The mouse pointer moves just fine, it's just that clicking on launchers or menu buttons in the panel doesn't do anything. Applets and application icons in the panel do *not* hang -- it's just the panel launcher and menu buttons that are nonfunctional.
if you could attach to the process and get a stacktrace with gdb that would be good (gdb attach $(/sbin/pidof gnome-panel), then bt full from the gdb prompt) also, doing gnome-session-remove gnome-panel followed by export G_SLICE=always-malloc; valgrind --tool=memcheck gnome-panel and waiting until it locks up and then giving the output might be useful.
I've been seeing this too on my x86_64 system for a long time (I never considered filing a bug for this my bad) this has happened to me with various versions since atleast FC-6, maybe even earlier. I think this always happens when I've just installed / updated an application which adds / changes a .desktop file under /usr/share/applications. I believe that the hang is in code that rescans /usr/share/applications, or it is related to the icon cache, but I could be wrong. There could be multiple hanger causes even. Scott, when you say leave on for atleast 2 days, could it be that you are installing updates and or new packages during this time? About some people seeing the icons disappearing, this happens when you force a redraw, for example by running the screensaver. The icons disappearing on a redraw is quite normal for a hanging app, so this is most likely one and the same problem. BTW, I believe that bug 224369, bug 247598, bug 242650, bug 233141 and bug 228559 are all dups of this. Notice that several reporters have made the same observation that I have, that this seems to always happen on upgrading / installing new applications. Ray let me know if you want me to close them all as a dup of this for you.
Ah, yea, if you want to dupe those, that'd be great (it's a bit embarrassing that there are so many duplicates of this bug, and I haven't moved any of them past NEW)

Hi, We no longer support Fedora Core 6 and I am currently trying to get my open bug count down to a more manageable state. I'm going to close this bug as WONTFIX. If this issue is still a concern for you, would you mind trying to reproduce on a supported version of Fedora and reopening? (this is a mass message)
