I took a look on keepassx v2 (alpha3) http://www.keepassx.org/news/2012/10/367

I was a little bit frustrated that there is no support for N900 or any other small displays as mentioned in roadmap: http://www.keepassx.org/news/2010/09/242

So I spent some of my free time with fixing it. I cloned the git (https://gitorious.org/keepassx/keepassx) to https://gitorious.org/~luf/keepassx/keepassx-n900 and add several features:
- decrease requested cmake version from 2.6.4 to 2.6.3 (on N900)
- add QScrollArea into Dialogs (for small displays)
- change signal CategoryListWidget::currentRowChanged to itemActivated (due to Maemo usage - change even during scroll only: http://forums.internettablettalk.com....php?p=1108063 )
- specify minimum height of icon lists
- fix columns in Settings (added colspan)

- Maemo only (#if(n)dev Q_WS_MAEMO_5:
+ removed Enty and Group actions from menu (as it should be performed via popup menu)
+ hides Cancel buttons because click outside dialog window is cancel. But it's unable to click outside MainWindows
=> I rewrite DialogyWidget to QDialogs
=> DatabaseWidget to exec dialogs
=> all dialogs to call QDialog:: accept() or reject()
=> change labels to Dialog captions
+ change height of some Dialogs
+ remove/hide some spacers

Right now I'm able to open some keepass v2 database and work with it.

If there is someone who wants to test it feel free to install it from http://merlin1991.at/~luf/keepassx or I uploaded it as attachement (few kB below the limit for .deb)

EDIT: this package was built againist PR 1.3 so the problem with installation should disappear.
