>Sure. Well, if evince is installed then it should exist in the XDG MIME database and therefore it should be present in the "Open with ..." file manager menu. Although which application will be launched on simple Open action is defined by order: 1) use user defined default application for that MIME type 2) use system defined default application for that MIME type 3) use last registered for that MIME type by user 4) use last registered for that MIME type by system When (1) is used - this is what we do when we associate some file with some application, as it was said. Usage of (2) is Debian-wide, you know, and it definitely has no relation to LXDE package but rather to evince package (which may set system-wide default to evince at installation and drop it at removal). I see nothing what could be done in regards of (3) and (4) as we cannot determine order in which packages (and especially user applications such as WINE ones) are installed, and there is no preference order in terms of XDG MIME database. Please, clarify what we can do in that regard, and probably we should reassign this issue to evince package instead if we decide it should be set as system default. Thanks.
