Comment (by dx):

 For the sake of clarity, the commit with the fix for the 2.x.y branch is
 902b1fd334bd, not the attached patch or the first linked commit.

 Some distros were affected because they backported the original gstreamer
 1.0 patch:

 * Ubuntu bug report:
 https://bugs.launchpad.net/ubuntu/+source/pidgin/+bug/1479715 - Stable
 release update template filled in, waiting for ubuntu devs to do the rest
 of the work, may take a few weeks to get the fix in ubuntu wily

 * Arch linux bug report: https://bugs.archlinux.org/task/46722 - Should be
 closed already

 * Fedora bug report: https://bugzilla.redhat.com/show_bug.cgi?id=1206363

 Test case, copied from the ubuntu SRU:

 1. Set the file descriptor limit low enough to be able to login, plus a
 few extra. "ulimit -Sn 20" works for me
 2. Start pidgin
 3. Tools menu -> preferences -> sounds tab
 4. Click "preview" 10 times or so
 5. Acquire crash
