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.

Additional info:
Comment 1 Alexander Todorov 2010-12-10 21:02:46 UTC 
Right-click works with http://www.youtube.com/watch?v=wyR0cBYUxUQ 

It's probably something about the website/video that causes the hang.
Comment 2 Martin Stransky 2010-12-15 10:59:46 UTC 
Do you use nspluginwrapper? Can you reproduce it without nspluginwrapper?
Comment 3 Alexander Todorov 2010-12-15 11:18:59 UTC 
I had nspluginwrapper-1.3.0-14.el6.i686 installed. Removing it fixed the issue.
Comment 4 Martin Stransky 2010-12-15 12:33:56 UTC 
Yes, I can reproduce the crash with npsluginwrapper, flash plug-in is struck somewhere in glib when npsluginwrapper is installed. I wonder why...

Comment 6 Martin Stransky 2010-12-16 11:25:40 UTC 
Well, it's because the two nested glib loops are waiting for the same content, 
context=0x8582a88 in this case. We need to attach the rpc handler to a different loop.

Comment 10 RHEL Program Management 2011-01-07 15:39:52 UTC 
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unfortunately unable to
address this request at this time. Red Hat invites you to
ask your support representative to propose this request, if
appropriate and relevant, in the next release of Red Hat
Enterprise Linux. If you would like it considered as an
exception in the current release, please ask your support
representative.
Comment 11 Martin Stransky 2011-05-04 10:04:35 UTC 
It should be fixed by new upstream version 1.3.2.
Comment 12 Martin Stransky 2012-08-03 10:35:22 UTC 
Flash is dead and closed source, closing as WONTFIX. You can imagine CANTFIX here as well.
