Comment 1 Len Lawrence 2015-09-06 18:37:13 CEST 
This needs a stack dump or stacktrace but I have no idea what packages are required.  Tried 'gdb pavucontrol' and came up empty.
There was a recommendation to try

 dnf debuginfo-install pavucontrol-2.0-6.mga5.x86_64

but dnf is missing from my system and does not appear to be an installable package.  And I do not know what else might be required.
Comment 2 Len Lawrence 2015-09-06 18:42:56 CEST 
However I found this in my home directory:

[lcl@difda ~]$ cat segfault

Comment 5 Nikita Krupenko 2015-09-12 21:02:21 CEST 
Confirm, I have crashes too. IIRC, crashes started after updating to gcc 5. Some programs started to crash too, but after updates is is fixed. May be pavucontrol needs rebuild?

After update it does not crashes.

Thanks Blino for fixing and Nikita for confirming. In the future feel free to close the bug if you're pretty confident all is well :)

Cheers!
