All reports should be submitted in English, as it is the common language for this bugtracker.

We are only able to accept bug reports in English since it is the common language used on this tracker.

You are welcome to create a new ticket about your issue in English. You can use an online translator, if it helps.
However, please search before writing a new bug report, as it's very likely that someone else already reported your issue before.
If you find an existing ticket about your issue, you can add a vote and any new information to it instead of reporting it yourself.
