#2938 ttk::style layout with empty -children silently disappears

[Thomas Perschak]

Environment Window XP, MinSys compiled TclTk 8.5.11, Theme winnative;

proc childerr {} {
toplevel .t
ttk::style layout Test.Tentry {Entry.field -sticky nswe -border 0 -children {Entry.padding -sticky nswe -children {Entry.textarea -sticky nswe}}}
ttk::entry .t.e -style Test.TEntry
pack .t.e -fill x -expand yes
puts a
ttk::style layout Test.Tentry {Entry.field -sticky nswe -border 0 -children {Entry.padding -sticky nswe -children {}}}
puts b
}

The procedure gets executed without error but "b" is not printed and the widgets appearance does not update. At least it looks like the interpreter stays healthy as there are no symptoms of high cpu load etc....
The more major problem is that the code after the ttk:style never gets executed.

thx

retested, still valid
