Consider filing a Support Request unless you are very sure you have found a bug.
Note that you can attach your motion config files and other supporting files to the bug report once it has been created.
Also note that if you want to copy/paste error logs and error messages and similar into a bug report you should put the entire text within <verbatim> and </verbatim> tags. Otherwise you do not get any line breaks. Text pasted into the "Verbatim Text" field are automatically placed between VERBATIM tags.
