severity 170711 critical thanks Hi, I ran into coredumps when using python-vtk, see bug #170498. I believe the coredumps are due to python moving from tcl/tk 8.3 to tcl/tk 8.4. Other python extenion modules are still built with the older tcl/tk, so you end up with both 8.3 and 8.4 loaded. I think this bug should be release-critical to hold up the move to "testing" until all the modules are in sync, right? -Steve
