What are you looking for exactly? Some full-fledged (likely
commercial) solution [1] or just some simple error report dialog?

I've done the latter in my own project with much success. However it's
coupled to some other stuff in the project so I can't really give you
a ready solution, but feel free to rip out what you can need.

- It uses PyQt to display an error dialog with all the logs and a
  restart button: [2]
- It calls that dialog from sys.excepthook: [3]
- It uses the logging module to log all log calls (debug loglevel) to
  the RAM and shows that log then: [4]
- It also integrates Qt warnings and Python warnings in the same log.
- It uses the faulthandler module to write a crash dump on segfaults
  and then displays the report window on the next start: [5]
- Some other useful information is gathered (version information, OS
  information, their configfile, commandline arguments, list of Qt
  widgets/objects, etc.).
- When the user clicks "Report", the full crash log is automatically
  sent to my pastebin via urllib: [6]

An example crashdump is at [7]. It's been some effort to set this up,
but it has proven to be incredibely helpful for debugging issues.
