Error in <TList::Clear>: A list is accessing an object (0x3e28b80) already deleted (list name = Browsables)

[Viesturs]

I installed a completely clean Delphes on lxplus

When I test it as outlined in ​https://github.com/delphes/delphes

./DelphesSTDHEP cards/delphes_card_CMS.tcl delphes_output.root z_ee.hep

I get an error:

• Reading z_ee.hep

Error in <TList::Clear>: A list is accessing an object (0x3e28b80) already deleted (list name = Browsables)

What is wrong?

This cause of this problem starts with adding folder to gROOT->GetListOfBrowsables():

​https://github.com/delphes/delphes/blob/master/modules/Delphes.cc#L72

then by deleting folder

​https://github.com/delphes/delphes/blob/master/modules/Delphes.cc#L83

and then by Root exiting the executable and deleting the folder that is already deleted.
One needs to remove folder from gROOT->GetListOfBrowsables() together with deleting it.
