Comment 5 for bug 668895

You patch now breaks it for osx-app bundled packages: the "Text file (*.txt)" is no longer listed in the 'File > Open…' dialog. A variant of the extension (with the <check> directive removed) is loaded from ~/.config/inkscape/extensions and listed as available file format.

Note that building inkscape with '--enable-osxapp' uses relative paths, see 'src/path-prefix.h'.

Tested and compared with r10017 and r10021 from <http://inkscape.modevia.com/macosx-snap/?C=M;O=D>
