This question already has an answer here:

I am trying to give some depth to my svg files. I have imported an svg file and then joined the curves together by grouping them. The extruding it self does not give any problems, however when i try to give it a bevel or adjust the offset these weird spikes stick out my object. Also, even though I joined the objects together i still can't extrude them all together. Am I doing the grouping wrong?
