More descritpive Traceback on observer failure

[bahman]

Hi,

If there is a mistake in code of an observer the tracback is similar to this:

Observer '<__main__.SimpleGroupWindow object at 0x11c8b5590>' with '_currentGlyphChanged' failed: 'NoneType' object is not callable

If the code is more than a few lines, it's very hard to find out where the problem originates without knowing the line. Is it possible to add the line number and more info to the Traceback?

Thanks

the traceback can indeed be printed!

up to RF3.5!
