I believe there is an error in the xfce-4.0.4-src.tar.bz2 file. It contains 2 libxfcegui4*.tar.gz files (one is apparently from cvs). A recursive diff shows that the following files are different in the 2 tars: session-client.c xfce_systemtray.c Which is the correct libxfcegui4*.tar.gz file for the 4.0.4 release? Thank you, Peter
