I discover that when I save a workspace containing a genefilter (pkg from Bioconductor) object I cannot open no more after. I have to restore the .RData file from a backup to be able to start R again. I didn't upgrade to Version 2.2 but I'm not sure that it will solve the problem.
Did anyone have encounter the same problem? Below is a short r session to reproduce the error: ...
