[horde] Fatal error in service Weather

[Alexandre DENIS]

Hi,

I have a Horde 4 install that has worked flawlessly for more than one year.

I have a weather widget on my portal page, and it stopped working today. When 
I login, I get a fatal error, "String could not be parsed as XML". I get the 
following in syslog:

Aug 24 14:21:16 jupiter HORDE: [horde] PHP ERROR: 
SimpleXMLElement::__construct(): Entity: line 1: parser error : Start tag 
expected, '<' not found [pid 11459 on line 268 of 
"/usr/share/php/Horde/Service/Weather/Google.php"]

11459 on line 268 of "/usr/share/php/Horde/Service/Weather/Google.php"]

If I manually go to other pages than the portal, e.g. /kronolith, it works.

My system is Debian stable, up-to-date. The latest Horde 4 upgrade was some 
weeks ago. I tried an upgrade today, but it didn't fix the bug. In particular 
I have:
Horde_Service_Weather     1.1.2   stable
Horde_Xml_Element         1.0.1   stable
horde                     4.0.15  stable

My questions:

-- does anybody have an idea why it broke today, and how to fix it?

-- as an emergency solution, how can I remove temporarily the weather widget 
from my portal page, since I am locked out from it?

Thanks,
-Alexandre DENIS.
