Codejam 2018 - Getting confusing runtime error

I am trying to solve Codejam 2018 Round 1B - Rounding Error.
I believe my solution should be correct. However, the system does not accept my code due to a "Runtime Error". I simply can't figure out what the error could be.
Here is my code:
# Codejam 2018, Round 1B: Rounding Error
from math import floor
def round_half_up(x):
"""Rounding to nearest integer with tie-breaker rounding up."""
return floor(x + 0.5)
def round_up_set(N):
"""Returns set of votes that round up given total number of voters."""
return set([i for i in range(1, N + 1)
if round_half_up(100*i/N) != floor(100*i/N)])
def get_percentage(num_voters, lang_votes):
"""Gets total percentage given list of vote counts and total voters."""
return sum([round_half_up(100*i/num_voters) for i in lang_votes])
def get_max_percentage(num_voters, lang_votes):
"""Find max sum of votes when rounding percentages of votes."""
voters_left = num_voters - sum(lang_votes)
round_up_votes = round_up_set(num_voters)
if len(round_up_votes) > 0:
min_votes = min(round_up_votes)
for i, votes in enumerate(lang_votes):
if votes not in round_up_votes:
extra_votes = min([i for i in round_up_votes
if i > votes]) - votes
if extra_votes < min_votes and extra_votes <= voters_left:
lang_votes[i] += extra_votes
voters_left -= extra_votes
while voters_left >= min_votes:
lang_votes.append(min_votes)
voters_left -= min_votes
if voters_left > 0:
lang_votes.append(voters_left)
return get_percentage(num_voters, lang_votes)
# I/O Code
num_cases = int(input())
for case in range(1, num_cases + 1):
num_voters, num_lang = [int(i) for i in input().split()]
lang_votes = [int(i) for i in input().split()]
max_percentage = get_max_percentage(num_voters, lang_votes)
print("Case #{}: {}".format(case, max_percentage))
This seems to run to completion without any runtime errors when I test it locally (even using a separate Python 3.5.2 distribution which should be closer to what Google Codejam uses - they use 3.5.3).
I can't come up with any input that the Codejam problem could be generating that would cause the program to exit with an error.
What am I missing?
