[pygtk] exception handling

[John Hunter]

If I raise an exception in a gobject timeout function, is there a way
for me to catch it hand handle it in the main thread?  Here I
try/except the "run" method, but the exception does not propagate.  I
recall there are difficulties in cross thread signal and exception
handling, and am wondering what the right approach is.   I am not
writing a UI here, just using the gobject event loop in a cron script.
 Here is some example code



import gobject

def ontimer(*args):
    print 'ontimer'
    raise RuntimeError('Ouch')
    return True


gobject.timeout_add(1000, ontimer)

loop = gobject.MainLoop()
try: loop.run()
except RuntimeError:
    loop.quit()
    print 'all done'
