Catching it and ignoring it as the OP was doing (or assuming it's some
particular exception) certainly is.
If you know (or suspect) that stderr isn't going anywhere that it will
be seen, then catching all exceptions at the top of your program and
logging them and exiting with an error status is a reasonable thing to
do.
#!/usr/bin/python
import sys,syslog,traceback
def main():
[...]
try:
main()
except:
syslog.syslog("%s: %s\n" % (sys.argv[0], traceback.format_exc()))
sys.exit(1)
If it's a GUI program, then popping up an error dialog instead of
sending it to syslog might make more sense -- if you can be reasonably
sure that the GUI framework is still operational.
