Short hint for all those who use vim and pathogen

Today, after updating my wokspace to latest version I encounter below error during vim running:

Error detected while processing function pathogen#runtime_append_all_bundles:
line    1:
E121: Undefined variable: source_path
E116: Invalid arguments for function string(source_path).') to pathogen#incubate('.string(source_path.'/{}').')')
E116: Invalid arguments for function 4_warn
Press ENTER or type command to continue

Quick look on pathogen runtime_append_all_bundles function and I found:

call s:warn('Change pathogen#runtime_append_all_bundles('.string(a:1).') to pathogen#incubate('.string(a:1.'/{}').')')

So simply replacing:

call pathogen#runtime_append_all_bundles()

with:

call pathogen#incubate()

in $HOME/.vimrc fix the problem.
