I can't install this from app manager and from terminal I see

Unpacking multical-date-widget (from .../multical-date-widget_0.1.0-4_armel.deb) ...
dpkg: error processing /home/user/MyDocs/.documents/debs/multical-date-widget_0.1.0-4_armel.deb (--install):

dpkg-deb: subprocess paste killed by signal (Broken pipe)
Errors were encountered while processing:

Is this a conflict with some other widget?
