TYPO3 Core

Working on current master (6.2beta3) I get this error when creating content elements.

SQL:

INSERT INTO tt_content (CType,starttime,endtime,layout,colPos,date,header_position,header_layout,text_align,text_face,text_size,text_color,imagewidth,imageheight,imageorient,imagecols,imagecaption_position,cols,recursive,menu_type,list_type,table_bgColor,table_border,table_cellspacing,table_cellpadding,target,spaceBefore,spaceAfter,section_frame,sectionIndex,accessibility_title,accessibility_bypass_text,sorting,pid,sys_language_uid,header,header_link,subheader,hidden,linkToTop,fe_group,categories,l18n_diffsource,crdate,cruser_id,tstamp,t3ver_stage) VALUES ('header','0','0','0','0','0','','0','','0','0','0','0','0','0','2','','0','0','0','','0','0','0','0','','0','0','0','1','','','256','1','','','','','0','0','','0','a:20:{s:5:\"CType\";N;s:6:\"colPos\";N;s:16:\"sys_language_uid\";N;s:6:\"header\";N;s:13:\"header_layout\";N;s:15:\"header_position\";N;s:4:\"date\";N;s:11:\"header_link\";N;s:9:\"subheader\";N;s:6:\"layout\";N;s:11:\"spaceBefore\";N;s:10:\"spaceAfter\";N;s:13:\"section_frame\";N;s:6:\"hidden\";N;s:12:\"sectionIndex\";N;s:9:\"linkToTop\";N;s:9:\"starttime\";N;s:7:\"endtime\";N;s:8:\"fe_group\";N;s:10:\"categories\";N;}','1389789503','1','1389789503','0');
