I know very little about python and nothing about twisted, so the chances of me fixing this with no more information than 'this is a bug in glib' in the bug is very slim. I would recommend to encourage the twisted guys to file an bug against glib upstream, and include relevant information. They should have some. How would they determine that this is a glib problem, otherwise ? I reopened the ticket on the twisted bugtracker and asked. http://twistedmatrix.com/trac/ticket/3981 Thanks Ah, so this is actually a pygobject2 issue. so the ticket says it's solved upstream: https://bugzilla.gnome.org/show_bug.cgi?id=481569#c82 not sure if it went into any release though Well I figure it can't have made it upstream. Since it's been working for ages in Ubuntu, but not in Fedora or Suse I suspect that Ubuntu must be carrying a local patch. This should be the one: http://git.gnome.org/browse/pygobject/commit/?id=a9c168c58cc6a449b51653417bf3f58bdd41457c Which is probably a revision of patch 61 here: http://patch-tracker.debian.org/package/pygobject/2.20.0-1 Is is possible to get this patch applied to a Fedora package, I'd be happy to test on both Fedora 11 and 12? This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Created attachment 461848 [details]
another test case that causes pygtk/twisted to get into a spin
The test case included in this bug did not trigger the problem for me on Fedora 14 x86_64 fully up to date. This one does.
The example test case I just posted is a simplified version of this one: http://stackoverflow.com/questions/3617772/how-to-spawn-a-browser This page also says: "This was fixed in pygobject-2.21,0 and pygtk-2.17.0" Which is clearly not the case... I've gathered a few links on my own bug tracker: http://winswitch.org/trac/ticket/90 Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. Please see comment no 9 and re-assign to Fedora 14. This easily testable bug affects all versions of Fedora since Fedora 12, not just Fedora 12. I have since created a new bug for it, hoping it would get some attention, to no avail.. https://bugzilla.redhat.com/show_bug.cgi?id=660137 |
