[R] Problem with tabbed notebook (tcltk, Iwidgets)

[Talita Perciano]

Hi,

I'm using R version 2.9.0 and I'm trying to execute an example using
tabnotebook from iwidgets. Unfortunately I get a problem as you can see
bellow:


> library(tcltk)
Loading Tcl/Tk interface ... done
> library(tkrplot)
> tclRequire("Iwidgets")
<Tcl> 4.0.1 
> 
> tt <- tktoplevel()
> tkpack(tn <- tkwidget(tt, "iwidgets::tabnotebook"))

 *** caught segfault ***
address 0xffffffb8, cause 'memory not mapped'

Traceback:
 1: .External("dotTclObjv", objv, PACKAGE = "tcltk")
 2: structure(.External("dotTclObjv", objv, PACKAGE = "tcltk"), class =
"tclObj")
 3: .Tcl.objv(.Tcl.args.objv(...))
 4: tcl(type, win, ...)
 5: tkwidget(tt, "iwidgets::tabnotebook")
 6: .Tcl.args.objv(...)
 7: structure(.External("dotTclObjv", objv, PACKAGE = "tcltk"), class =
"tclObj")
 8: .Tcl.objv(.Tcl.args.objv(...))
 9: tcl("pack", ...)
10: tkpack(tn <- tkwidget(tt, "iwidgets::tabnotebook"))

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
Selection: error in background error handler:
out of stack space (infinite loop?)
    while executing
"::tcl::Bgerror {out of stack space (infinite loop?)} {-code 1 -level 0
-errorcode NONE -errorinfo {out of stack space (infinite loop?)
    while execu..."

Anybody could help me?

Thanks,
