Comments:	By: David Brillert (aragon) 2009-07-15 10:07:12 uploaded valgrind1crash15072009.txt after restarting valgrind and valgrind crash This crash occurred on new checkout of revision 206273 By: David Brillert (aragon) 2009-07-23 14:39:15 Unable to reproduce. Please close ticket By: David Brillert (aragon) 2009-07-23 14:40:42 Unless a developer wants to look at the valgrind and determine if this is a bug that should be fixed...
