That is bad news if the jum build does the same thing. Your system doesn't sound healthy. In most cases a permission & system repair should fix these issues. You may need to restart from the installation disk & use disk utility to repair your mac osx. If you have any other 3rd party utilities such as Norton Utilities, DiskWarrior, TechTool Pro or Drive 10 or others, give them a run over of your OSX. There may be a directory data miscount error or something that's causing issues.
