Given the error message, a good guess is probably that the trio package 
is used.
The CRAN checks showed also some (maybe unrelated) problems with the 
package under R-devel recently. It is always a good idea to write to the 
package maintainer (hence CCing Holger Schwedner) - including 
reproducible code in the message, of course.

Best,
