[R] problems with rq.fit.sfn

Dear all,

I am running a quantile estimation with Sparse matrix and when I run the procedure rq.fit.sfn I receive the following warning: tiny diagonals replaced with Inf when calling blkfct. Does anyone knows exactly what does it mean? What's this kind of error? Should I get worried about this message?  The matrix I use is a full rank matrix (and indeed I do not have any message about singularity problems).
Many thanks for your help
