FAQ:How do I submit a bug report?
From MakeHuman Community Wiki
If you have found something that you think merits a bug report, please submit it on the bug tracker.
The credentials on the bug tracker are the same as on the forums, so if you already have a forum login, use that to log in on the bug tracker.
NOTE: if you experienced a crash rather than a glitch, please also read this before submitting your bug report: FAQ:How to provide a makehuman log for a good bug report?
