I have an example of the libc crash. Should I attach it here or make a new thread? I'm not really sure it's related but it's very similar in behavior.
I also have a running hypothesis of a trigger for a crash. from what I can tell, it seems that it only occurs when all steam windows are closed and steam is running from the tray only. My evidence isn't concrete yet but it's been something I'm collecting info on.
I had the same issue today on Ubuntu, restarted after an upgrade of a buncha stuff. The first thing I did was go to the gnome menu, Right click on the steam logo and hit Library. after a moment I get a crash. Since then I've been unable to reproduce.

i'd like to clarify: i earlier noted that i thought the crash only happened when the main steam window wasn't open. i have learned this is not the case. it crashes whenever it wants to.
all three different crashes (two variants of libdbus and one involving libc) i experienced went away after i deleted my .steam directory. if someone encounters this issue in the future try this first.
Just got this problem, and removing $HOME/.steam fixed the issue. Thanks
Your system information
Please describe your issue in as much detail as possible:
After a random period of time, steam crashes without any notice. I can't seem to correlate the crash to any particular activity. Some days it doesn't happen at all, some days it happens multiple times.
The dmesg output for the crash is:
an example log file for one of the crashes can be found here
the minidump for that crash can be found here: crash_dump.zip
my steam hardware info is here
I believe this bug may have been briefly noticed by kisak-valve in this thread but that wasn't the issue at hand.
there's also this issue which may be related, but i'm not positive.
there's a second error with the same symptoms that pops up on occasion that indicates a problem with libc instead of libdbus, but I haven't managed to capture that happening yet with full logging. the vast majority of the time, the libdbus error is the cause.
