This is for qeradiant, guess the error apply but don't know if the debug tool works in mohradiant. Try and find the ¤#%# brush and delete it.

WARNING: Node without a volume / node has 0 tiny portals

An infinite brush. Delete it. The latest build of GtkRadiant has a debug tool that can help the mapper track down infinite brushes. Go to the BSP menu and select No_Vis (No light). After the compile process, a window will open up--assuming you've got bad brushes--and the first brush in the list will be selected and visible in the Z-Window. Merely press Backspace to delete this brush and repeat the No_Vis process. Or, you can use the Find Brush command (Misc menu) to find and then delete those bad brushes.
