Server side sort sSortDir somtimes is strange

caiofior

Server side sort sSortDir is ok, is alternatively "asc" or "desc" in every column except in data use. The data format is "2013-05-31 19:18:05" and the sSortDir returned is "d" the first time, than "e", "s","c". Every time this sequence is repeated.
I fixed the issue with an appropriate php scritp, but the bug still exists.
