If your SNMP device used the type "Opaque" to send floats the values were not formatted properly which caused some crashes later.

The error occured if Checks tried to use these corrupted values. Error patterns looked like this:

ValueError: could not convert string to float: '\x9fx\x04?B\x8f\'

Now the Opaque value is formatted.
