Springer DOI fails

Hello, I've noticed that there are some problems when looking for a Springer DOI, like these ones: 10.1007/978-3-642-20511-8_20 10.1007/978-3-642-28108-2_19 I know it's a known bug by looking at old threads here on the support forum, and I wish to know if there is any solution to the problem. I'm using Mendeley 1.9.2 on Linux. Thank you.
