Confirming the bug and editing description ** Description changed:
- Binary package hint: tortoisehg + How to reproduce: + - create new file in the repository: + touch newfile + - schedule the new file for commit + hg addremove + - start hgtk commit + hgtk ci + - add a comment and commit using the GUI + - exit hgtk - I don't have a reproducible test-case yet, hope this stacktrace helps. + Expected Result: + -hgtk terminates + + Actual Result: + -hgtk does not terminate + -Ctrl-C does not terminate it + + This happens with python2.6 (also on Debian unstable), but does not happen with python2.5. + Still present with tortoisehg 0.9.3-1. + + The hgtk code tries to exit by raising a SystemExit exception, but the + process never terminates. Adding an explicit sys.exit() does not change + the described behavior. + + Attaching to the dangling process with pdb shows: +
