"System error while retrieving price quotes"

[Oliver D. Iberien]

Hi,

Price quotes in GnuCash 1.8.9, SuSE 9.1, compiled from source, have suddenly 
stopped working after ten months. GnuCash puts up an error stating "System 
error while retrieving price quotes." Running it in debug for some reason 
does not even show this failure happening or the posting of the error 
message, so I don't know where to begin. I don't see anything in the archives 
about this. Can someone help? Thanks.

Oliver
