I will reassign this bug to libavifile since file overwrite errors occur at the same time with other packages. Here is the list of packages I found and the list of offending path names: avifile-mad-plugin/1:0.7.48~20090503.ds-3: /usr/lib/avifile-0.7/mad_audiodec.so avifile-mjpeg-plugin/1:0.7.48~20090503.ds-3: /usr/lib/avifile-0.7/osmjpeg.so avifile-vorbis-plugin/1:0.7.48~20090503.ds-3: /usr/lib/avifile-0.7/vorbis_audio.so -Ralf
