list index out of range

I am getting the following error when I try to execute
./gitstats -c start_date="$(date +%Y-%m-%d -d "3 month ago")" "/repository/<repo_name>/.git" "/repository/gitresult"

Error:
[0.00403] >> git shortlog -s --since="2018-05-29" "HEAD" | wc -l
[0.00518] >> git show-ref --tags
[0.00352] >> git rev-list --pretty=format:"%at %ai %aN <%aE>" --since="2018-05-29" "HEAD" | grep -v ^commit

File "./gitstats", line 1465, in run

File "./gitstats", line 338, in collect
timezone = parts[3]
IndexError: list index out of range

Surprisingly, It works when I change the date to 4 month ago. I have no idea why it the error is occurring. Is it something related to different commits in repository?

You can add the following code

1. After line (for line in lines):
   if len(line) == 0:
   continue
2. After line (for revline in revlines:)
   if len(revline) == 0:
   continue

Non of them don't work for me

this issue is caused by there is no commits after the start_date specified.
