Checking to see if anyone notices this before filing a bug report. One of the things is that when I select om-welcome from the Application Launcher it does not open. If I run it from Konsole I get a plasmashell dialog box that indicates segfault. In KDE Menu Editor the path (/usr/bin/om-welcome) appears to be correct.
