Finance::Quote cannot download information from tickers with + or - in the symbol

Binary package hint: libfinance-quote-perl

Finance::Quote will not get information from Yahoo! when the stock tickers contain either the plus (+) or minus (-) sign in the stock symbol. I have seen this in funds listed on the Mexican market, but I assume this is true for any market. This happens with various different symbols, e.g. ACTICOBB-1.MX, ACTIVCOB-1.MX, I+GLOBDB-F.MX, and others. Also, GnuCash does not report data on the MXN currency, but this may be another bug altogether. When getting quotes in GnuCash I get the following message box:

Unable to retrieve quotes for these items:
  FUND:IXEEUROBF1.MX
  FUND:ACTIVCOB-1.MX
  FUND:ACTICOBB-1.MX
  FUND:IXEMPM+BF1.MX
  CURRENCY:MXN
Continue using only the good quotes?

Here is the output of gnc-fq-dump for ACTIVCOB-1.MX:

gnc-fq-dump -v yahoo ACTIVCOB-1.MX
