Bug 189278

*** Bug 189307 has been marked as a duplicate of this bug. ***

Possibly one or several of these? Of all of them, the only one I'm actually
seeing in my extension list is langpack-nb-NO.

[nicholas@entropy extensions]$ xmlwf */install.rdf
langpack-ko.org/install.rdf:2:0: xml declaration not at start of
external entity
langpack-mk.org/install.rdf:2:0: xml declaration not at start of
external entity
langpack-nb-NO.org/install.rdf:10:34: not well-formed (invalid
token)
langpack-pa-IN.org/install.rdf:2:0: junk after document element

[changing summary to be more specific]

Sorry to bother you again but the problem still exists with the new update.

I removed the package 1.5.0.2-1.1.fc5 and installed 1.5.0.2-1.2.fc5 and the same
message appears.

langpack-pa-IN.org is still included.

I'm having the same problem. Installed the Firefox update yesterday and the new
update today, 1.5.0.2-1.2.fc5 and both times on first run I received the error
message:

"Firefox could not install this item because "install.rdf" (provided by the
item) is not well-formed or does not exist. Please contact the author about this
problem."

Be aware that as far as I can see, all the language packs still belong to
1.5.0.1 and were not upgraded to 0.2.

Oh... and https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=189444 might be a
duplicate.

I can reproduce the bug by removing ~/.mozilla 

# /etc/cron.daily/slocate.cron
# rm -rf `locate langpack-pa-IN`
# rm -rf `locate langpack-nb-NO`
# rm -rf `locate langpack-ko`
# rm -rf `locate langpack-mk`

The error disappeared after the last command. Whether that means that -mk was
the offending item or that all of them were, is an open question. 

I can reproduce this error message on my test system as well.
Here is a screenshot captured.

When I was trying to view the HELP on
 System->Administration->Server Settings->Services

I would get the rdf error dialog.

I then did the /etc/cron..  (but I only had mlocate, not slocate)
rm ..
rm ..

as indicated below.

Now, I get a new error dialog message:

Close Firefox
Firefox is already running, but is not responding. To open a new window, you
must first close the existing Firefox process, or restart your system.

???
Since I can open a new Firefox window without any problem and in fact am writing
this message in a Firefox window, I wonder whether this is a bogus message.

(Besides, I am in the middle of another project and have 18 Firefox windows open
and don't want to close them all just yet..)

Ahah, I noticed that there was still the 'Malformed... install.rdf' error dialog
still open from a previous try at 
  System->Administration->Server Settings->Services

When I closed this window, the HELP window:
  Services Configuration Tool - Mozilla Firefox
opened up.

So the above 'Close Firefox' error message was complaining about just the one
error dialog window, not all of Firefox..  

I run 
# export LANG=ru_RU.UTF-8
# strace -f firefox 
and "Mailformed ..." dialog shows during opening file
/usr/lib/firefox-1.5.0.2/extensions/langpack-pa.org/install.rdf

This XML is really mailformed.
Removing this file solve the problem for ru_RU.UTF-8 locale.

When I originally installed FC5, the processor load was running about 35-65%
most of the time (dual xeon..) without doing much at all. Firefox was open with
a number of windows.

After the "rm -rf `locate langpack-pa-IN` ..etc" was run, the processor load
dropped off to normal (a few percent..). I don't know what was sucking up the
power, but am glad that it went away.

This was fixed in one of the updates.
