Issue Report: Segfault during long downloads
I've had this happen a few times. This is the most recent I got (besides the one that crashed my client while typing up this report). The segfault occurs (it seems) while downloading a game. I had it happen with SS3:BFE before, but wasn't sure entirely what happened. It only happened once on SS3:BFE, but it's happened about half a dozen times or so with TF2. Mind you, this may be symptomatic of the TF2 install bug.

Pastebin of the crash (with a repeating error before hand): http://pastebin.com/9qG3Xjg5

I’ve had flaky behaviour from downloads too, but have not been able to get it to crash or produce any debug info :\

Your pastebin only includes 2 lines of crash info, the last lines - as the other gtk-WARNINGs are related to running steam on 64bit.
Could you find the related crash dump file in /tmp/dumps/ and attach it?

Posted this on another thread, thought to include it here instead:


I was sleeping and TF2 was left dling.

(steam:19294): Gtk-WARNING **: A floating object was finalized. This means that someone
called g_object_unref() on an object that had only a floating
reference; the initial floating reference is not owned by anyone
and must be removed with g_object_ref_sink().
success = yes

I just checked the logs and didn't actually find anything. I've tried on two systems and the logs seem to be unruly in their placement. On ubuntu, there was nothing relating to it in that folder. On Mint, it said that there was a log file at /home/josh/Steam/ (which there wasn't)

Since switching to Mint 13, 32-bit, the issue seems to have stopped occurring all together.

I posted a backtrace on something that sounds very similar. Unfortunately, I have no clue where my old thread is. Is there someplace where my thread subscriptions or old posts are stored?

It seems to be extra crashy when attempting to download more than one game at once

Thanks. We are aware of this issue and are working on it. Fixes coming soon.

Sweet. Thanks, Scott.

I also have this problem.
It crashed when downloading any game (TF2, TF2 Beta, Serious Sam 3).
But, it would only crash if steam was minimized in Unity. (By pressing the "x" on the steam window).
If the steam window is left open (in the background), the download continues without problem.

Same problem here.
Crash while downloading Team fortress 2.
Thanks for working on it.
