Hi,
I get a crash when I try to draw a 2D histo from a tree without giving the name of the histo. I include a small script that reproduces the bug. Also some extra info and a stacktrace from gdb. To test the
script run it with
.L triggbug.cxx
root> triggbug() //should work
roo> triggbug(true) //should crash
