commit 85609edb2922ff8c206e34cff57daea60e4110c5
Author: Dodji Seketeli <dodji seketeli org>
Date:   Tue Nov 9 12:32:03 2010 +0100

    Restart without exception (Closes: #634406)
    
    	* src/persp/dbgperspective/nmv-dbg-perspective.cc
    	(delete_visual_breakpoint): Do not throw an exception when we
    	can't get the source editor of a given breakpoint. That just
    	likely mean 1/it's an in-asm breakpoint 2/we haven't disassembled
    	that part yet.
