[Daniel T Chen (crimsun)]

Is this symptom reproducible with the latest version of pulseaudio in jaunty?

[Fernando Miguel (fernandomiguel)]

Yes.
It just happened a sec ago

Program received signal SIGSEGV, Segmentation fault.

That isn't the latest version of pulseaudio in jaunty.

[Fernando Miguel (fernandomiguel)]

yeah it got stuck in queue on NM

This should be it:

pidgin hasnt crash yet. i'll get back to you in a few hours. ping me, if i forget... thanks

spoke too soon:

it happend seconds after i install vlc-plugin-pulse to test bug 295519. dont know if it is related

[Fernando Miguel (fernandomiguel)]

removing vlc-plugin-pulse stops pidgin from crashing! how strange is that

[Daniel T Chen (crimsun)]

Is this crash only reproducible with vlc-plugin-pulse installed and vlc running alongside pidgin?

[Fernando Miguel (fernandomiguel)]

i dont even have VLC open, (nor do i have vlc-plugin-pulse now installed) and pidgin has been crashing all morning!

Would u like a new full backtrace of the next crash?

where would I find PA logs to see if it maches/triggers anything from pidgin crash?

[darkrain42 (darkrain42)]

I believe you need to run
`handle SIGPIPE nostop`
in order to get a usable backtrace. Your two backtraces so far have just stopped on SIGPIPE, which indicates that the socket (for an OSCAR and XMPP connection respectively) has been closed (which is not a SIGSEGV)

[darkrain42 (darkrain42)]

I'm also a little confused how gtkmain.c seems to have debug symbols but the libpurple doesn't. Make sure you have the appropriate debug libraries installed...

[Fernando Miguel (fernandomiguel)]

Thanks darkrain42.
I've installed the remaining debug libs.

where should i ran handle SIGPIPE nostop ?

in the gdb console?

I think i found the reason

Exaile announce plugin to write the music to pidgin.
When I press play, ot pause, it will crash most of the times.

The fork() rework is in 0.9.15-test5.

[Steve Dodier-Lazaro (sidi)]

Hello,

I do not understand how Exaile is linked to this bug. Could the authors of the bug please explain what in Exaile exactly causes the bug to happen, and provide the steps to reproduce in order to trigger it ?

Does it still happen with the latest PulseAudio version ? Does Pidgin also crash when Exaile is not installed ?

Thanks in advance.

[Fernando Miguel (fernandomiguel)]

this has been fixed a long time ago. sorry for not closing sooner .

[Michael Alexander (ftmichael)]

I'm having this exact issue ever since installing Ubuntu 15.10 (Wily Werewolf). It was never an issue before. I had my Pidgin sounds set to use ALSA. Changing them to "Automatic" made no difference. Pidgin crashes and closes itself out seemingly at random, whether I'm using my computer at the time or not. No connection to playing other sounds or videos.

installed libpurple version is 2.10.11
installed pulseaudio version is 1:6.0-0ubuntu13

Crash error contains this line:
Pidgin GStreamer-CRITICAL **: gst_poll_get_read_gpollfd: assertion 'set != NULL' failed

It looks to be the same as this bug from 7 years ago: https://developer.pidgin.im/ticket/7519

Some good discussion is here: https://bugzilla.redhat.com/show_bug.cgi?id=470000

Everything I'm finding on this is from 2009, though. I don't know why it's suddenly appeared in a fresh install of Ubuntu 15.10.

[Richard-purdie-1 (richard-purdie-1)]

The issue in 15.10 is a different problem, likely in pidgin 2.10.11 where each time a sound plays, it leaks a socket pair, eventually running out of files. I'd guess its fixed in 2.10.12 with the commit "Remove Gstreamer pipeline after playing a sound".
