Description:
when mysqldump runs with --master-data on windows, it somehow makes the server block any other action and new connections afterwards.

How to repeat:
C:\mysql_logs>net start mysql
The MySQL service is starting.
The MySQL service was started successfully.

C:\>mysqldump --all-databases --master-data -u root -p --flush-logs

Thank you for the bug report. Could you please provide your my.ini file
I was not able to repeat with a source server built 5 days ago.

I don't have access to that machine anymore, but aside from a normal default installer-generated my.ini I think that those options were enabled:

log-bin
log
log-slow-queries
log-output=FILE

Thank you for the report.

Verified as described with version 5.1.19

Option log is cause.

Most likely fixed. I was able to reproduce in 5.19, but I cannot repeat in 5.1.20+.
