with IMAGES defined there is a segfault at line 107 of gtkImage.cc because filter is not yet instantiated (ie, the draw() call occurs before we have setup the filter yet). Also, I get lots of Tagstack Overdrawn messages -- this is not good and liable to cause problems :) Otherwise, I seem to get random crashes and gdb is not helping me find them :) [I seem to have a non-thread aware version] Andrew
