By default Xubuntu opens all OpenDocument MS Office and other word processing and spreadsheet files in Abiword and Gnumeric. That's fine on a default installation where only Abiword and Gnumeric are installed.
However when the user installs LibreOffice, these files are still being opened by Abiword and Gnumeric. This leads to the strange situation that if you save a text document in LibreOffice in its default OpenDocument format, and you double click on the file in XFCE later on to continue working, the file is opened in Abiword, causing loss of formatting. At least OpenDocument should be opened by LibreOffice if it's installed, as OpenDocument is a first class citizin in LibreOffice, while it's not in Abiword and Gnumeric. As LibreOffice also has excellent support for MS Office file formats and others, these should be assigned to LibreOffice too.
I attach a patch to /usr/share/xubuntu/applications/defaults.list which changes most formats to LibreOffice if the user installed it. On a default installation, nothing changes and Abiword and Gnumeric are still default.
