bug#43606: [IceDove]: Preferences does not open

[testerman--- via Bug reports for GNU Guix]

Hello All,

I tried using IceDove for the first time and found out that 'preferences' 
dialog does not open.

Got an error related to "XML Parsing Error: undefined entity".

The paste-bin of the full error, http://gg.gg/Guix-IceDove

Cheers,
Guix User.
