Package: recordmydesktop
Version: 0.3.8.1+svn602-1
Severity: important
I tried using gtk-recordmydesktop to record a session with sound
(checked the sound box in the GUI), but was told that recordmydesktop
segfaulted. When I test on the command line, I get the same error.
This is after I modified the default device from DEFAULT to pulse, to
try to use the pulseaudio sound system as described on
<URL:
https://wiki.archlinux.org/index.php/RecordMyDesktop#No_sound_with_PulseAudio >.
Is it possible to record sound when using pulseaudio on Debian? Is
there some other way to get audio recording working? Perhaps
recordmydesktop should be changed to report an error instead of
segfaulting?
This is the output from valgrind.

I tested this on Buster, and the command line run did no longer
segfault.
