Red Hat Bugzilla – Bug 505949
applications - system tools causes menu to disappear
Last modified: 2010-06-28 09:00:51 EDT
Description of problem:
(I'm not sure what component to use in this report - I assume you'll reassign to the right one.)
I've recently changed to fc11 and I notice that when I click on the applications menu (I guess this is gnome) I see submenus for accessories, games, etc. but when I get to the last one, system tools, the menu disappears. In fact, so do the top and bottom panels containing the munu bar, click, etc.
These then reappear. So far I've not been able to find out what is (or should be) on the system tools menu
Version-Release number of selected component (if applicable):
yum log says

and for that matter

click on applications, put mouse over system tools
can you attach to your panel with gdb and get a stacktrace when that happens ?
in a terminal, do
then reproduce the crash, go to the gdb prompt and type bt

unfortunately this doesn't work - it starts again before I can do the next line
> gdb gnome-panel
What I did manage to do was attach to the process

I then caused the crash -- I actually saw the submenu while it was frozen.
In fact I couldn't get the attention of any of the X windows, and had to go
to terminal f2 to kill it.
So I couldn't get the backtrace. Here's the transcript:

[I don't know whether it was here or the line above where I killed from f2]
Detaching from program: /usr/bin/gnome-panel, process 4793
Quitting: ptrace: No such process.
Hmm, so maybe I could do all this from f2 ?

Looks like one of the icons is a bad svg file that causes librsvg to crash.
Workaround would be to change the icon theme. But it would be really good to find out which of the icons in the system tools menu this is, so that we can a) fix the icon and b) stop librsvg from crashing on it.
This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '11'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 11's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 11 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
just moved to fedora 12 -- seems ok there
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
