First of all Thanks!
Have to say this would be amazing to use in Maemo and in the Future on Meego Tabs etc.
With CSSU I however cannot get the filedialog to work so I cannot open PDF or save etc. Made bug already also. Hope we get some love soon. Maybe some votes get it done. https://bugs.maemo.org/show_bug.cgi?id=12220
Also have the most stable patches from here: http://sourceforge.net/projects/xournal/forums/forum/554377/topic/4491300 been included in the devel version?
Just thought that this would probably also support the developement upstream. This way they would get reports of the working paches that are tested somewhat more and could include them in their next stable release.
Nice work anyhow.
