Reproduced with 3.4.4 and a 3.5 daily build of early december 2011. Uninstall leaves behind a "c:\program files\Libreoffice ${VERSION}" directory with: LibO-dev3.5: - share/prereg/bundled/: extensions.db, lastsynchronized - share/prereg/bundled/registry: 7 subdirectories names com.sun.star.comp.deployment.*.PackageRegistryBackend, with various files in subdirectory LibO-dev3.5 & Libreoffice 3.4: - program: lots of .pyc files Only Libreoffice 3.4 (but probably I just did not have non-bundled shared extensions on LibO-dev3.5) - share/uno_packages/cache/uno_pacakges/: *.tmp, *.tmp_. Each .tmp_ subdir as a .oxtproperties file and a corresponding .oxt subdir
