So I visited the link you gave and clicked the green arrow to "to add Maemo Qt4 repository in your applications manager". So this created a catalog, then refreshed. Nothing else was installed. Read forum info and followed a suggestion to "sudo gainroot", then "apt-get install keepassx" at a X-Term. This actually went and retrieved, then installed all the Qt4 dependencies and also fetched the keepass app. Install was successful, but no app icon was installed into the app launcher. I had to launch it from the X-Term "/usr/bin/keepass &". Weird.
