Description Jeremy Rimpo 2014-08-24 19:27:24 UTC 
Description of problem:
On a fully upgraded F21, pavucontrol immediately crashes with a segfault.

I believe this is a duplicate of #1133272.

In the console, there are several GLib-GObject-WARNINGs about deprecated functions prior to the segfault.

Version-Release number of selected component:
pavucontrol-2.0-7.fc21

Additional info:

[PATCH] Reference the widget before returning it from ::create methods

Nasty bug, just spend a couple of hours debugging this. This patch fixes it. For details see the commit message inside the patch.

I'm somewhat amazed that this works for F-19 and F-20 as is, but since it does I'm starting builds for F-21+ with this fix in.
Comment 16 Igor Gnatenko 2014-08-28 11:33:38 UTC 
Yes, this fixes problem.
Comment 17 Fedora Update System 2014-08-28 11:44:28 UTC

Comment 20 Peter H. Jones 2014-08-31 15:57:17 UTC 
Works fine in a custom live spin. I had to get the new version from koji because today's (Aug 31, 2014) spins appear to be a 2.0.7.

Installed pavucontrol-2.0-8.fc21.x86_64 on 28-Aug about half an hour after it was built. Been working properly ever since.
