RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Cannot reproduce for 100%, but I'm able to reproduce with multiple retries.
Comment 12 Ray Strode [halfline] 2014-08-22 20:17:19 UTC 
So this is a race condition sort of inherent in how GSimpleAsyncResult works in the version of glib we ship in rhel6.  It's possible for an asynchronous operation to finish and the associated callback to get called just as the operation is cancelled.  That's what's happening here, and so the callback is getting called with freed user data.  

Later versions of glib make it possible for the implementor of the async operation to close this race with a new function:

g_simple_async_result_set_check_cancellable

but getting this api added to rhel6 glib and then changing gtk to use it  doesn't seem worth the churn. especially since GSimpleAsyncResult has been superceded these days by GTask

The simplest patch is to store the cancellable on the source object as object data and check if it's cancelled at the operation finish time (in addition to the g_error_matches (error, G_IO_ERROR, G_IO_ERROR_CANCELLED) checking already being performed)

gtk2 is already on the approved components list and i have a patch so devack+
