How to preserve all information of an error when using an error handles

Hellow,

i have implemented an error handler that takes an screenshot when sikuli can not find an image. The problem is that now, all the information that sikuli usualy gives about the class, the function and the line where the error has produced doesn't appear in the logs.

try:
    ClassX.function1()
    ClassX.function2()
    ClassY.function1()
    ClassY.function2()

except FindFailed:
    print sys.exc_info()
    path = getBundlePath() + "\\..\\"
    name = "error.png"
    Common.takeAScreenshot(path,name)

I have found that the command sys.exc_info() gives a part of this information, but not the whole error.

Anyone knows a possible solution?
