SCRUM, how to handle bugs in the sprint and how to time estimate bugs
I'm working in a SCRUM project writing firmware code in C for an ASIC. 

Every so often we have really hard to find bugs. But how do I time estimate these bugs? 

I always tell the SCRUM master I do not have the competence to estimate them because I really hate time-estimation of bugs.

How do you guys handle this in your SCRUM-projects?
