[R] strange error in mtrace

Dear useRs,

I am experiencing very strange error with Mark Bravington's package "debug". I haven't seen them before.

Here is the sample session

> library(debug)

Loading required package: mvbutils
MVBUTILS: no "tasks" vector found in ROOT Loading required package: tcltk
Loading Tcl/Tk interface ... done
> x<-function() return(1)
> mtrace(x)
> x()

Error in attr(value, "row.names") <- rlabs :

        row names must be 'character' or 'integer', not 'double'
> mtrace(x,FALSE)
> x()

[1] 1
> mtrace(x)
> x()

Error in attr(value, "row.names") <- rlabs :

        row names must be 'character' or 'integer', not 'double'

This happened with any function, which I tried to debug.

I use R 2.4.0 on Linux and on Windows.

debug version is 1.1.0,
mvbutils version is 1.1.1

on both systems.

Linux R was compiled from sources.

The packages were installed from the Internet repositories using install.packages function on both systems.

update.packages only asks for repository for current session, and does nothing, which means, that everything is of the latest version.

What could be wrong?

Best regards,
Vladimir                mailto:wl@eimb.ru
