Thanks for your bug report. Could you try to install libgtk2.0-0-dbg, liblib2.0-0-dbg and gnome-panel-dbg and attach the output of bug buddy (as a file) again? Could you try to translate the lines with "** (gnome-panel:11520): WARNING **:"?

[Evandro Pastor (evandrolinux)]

Daniel:

Follow the translation:

Error in line 4: Caracter not read in the beginns name of entitie; the character begins a entity; if these commercial e (&) is not supouse to be a entitie, cover-it with &amp (&).

[Sebastien Bacher (seb128)]

Does it happen if you move your ~/.recently-used somewhere else. Could you attach this file to the bug or have a look if there is a mention of "&"? An application is probably breaking that file, ooffice is known to have a such issue

[Evandro Pastor (evandrolinux)]

Sebastian, there is a only one entry in recenlty-used file with "&" caracter:

<?xml version="1.0"?>
<RecentFiles>
  <RecentItem>
    <URI>file:///home/luis/clientes/juju%20&%20kiki/estoque%20181005.sxc</URI>
    <Mime-Type>application/vnd.sun.xml.calc</Mime-Type>
    <Timestamp>1137577158</Timestamp>
    <Groups>
      <Group>OpenOffice.org</Group>
    </Groups>
  </RecentItem>

[Sebastien Bacher (seb128)]

Thank you, the issue is openoffice doesn't escaping that file correctly, that's known as bug #24327

[Evandro Pastor (evandrolinux)]

This issue appear not only in openoffice. I've create a text file whith "&" and gnome-panel crash again. I've uninstalled openoffice to verify that, and chrash appear again.

[Sebastien Bacher (seb128)]

the issue is with whatever application which writes a "&" to the .recently-used without escaping it, openoffice had a known bug about that which is fixed now, if you find another app doing that too feel free to mention which one

[Ondřej Nový (onovy)]

try to remove ~/.recently-used file, logout, login, then create file with '&' and open it. i think, it will not crash :)

[Evandro Pastor (evandrolinux)]

Sebastian, in that moment, the user was using a bittorrent.
Ondřej, ive tried that, and don't work. I've to rename all archives to solve the problem.

A ubuntu version was: 5.04 (fresh install) upgraded under apt to 5.10 version with all updates until april 19.

[Lionel Dricot (ploum-deactivatedaccount)]

Anyway, Gnome-panel doesn't have to crash if he receive a bad string. He doesn't have to crash ever... ;-)

[Evandro Pastor (evandrolinux)]

I understand that Lionel :) But have any possibility to gnome, or any componnent of it, receive ant to treat this `bad string`? I'ts just a idea ;)

[Ondřej Nový (onovy)]

Note than the current dapper version doesn't crash on escaping issue but
ignore the recently-used entries rather
