When configured not to use themed widgets gitk may crash on launch with a message that says that the image "bm-left disabled bm-left-gray" doesn't exist. This happens when the left and right arrow buttons are created. The crash can be avoided by configuring the buttons differently depending on whether or not themed widgets are used. If themed widgets are not used then only set the images to bm-left and bm-right respectively, and keep the old behavior when themed widgets are used. The previous behaviour was added inf062e50fto work around a bug in Tk on OS X where the disabled state did not display properly. The buttons may still not display correctly, however the workaround added inf062e50fwill still apply if gitk is used with themed widgets. Make gitk not crash on launch when not using themed widgets.
