Details of the issue

Steam doesn't show webpages. Stdout is full of messages like this:

/home/fingercomp/.local/share/Steam/ubuntu12_64/steamwebhelper.sh: line 5:  3067 Illegal instruction     (core dumped) ./steamwebhelper "$@"

Each time this message is printed, a core dump is generated. Here's what happens in the syslog. The info about coredump returned by coredumpctl.

I took the coredump and used gdb to see what instruction makes steamwebhelper crash. Here's it:

0x5631503e8aba <_ZN10CCEFThread14RunSingleFrameEv+58>   movddup %xmm0,%xmm1

It turned out to be a part of SSE3 that my CPU doesn't support:

cat /proc/cpuinfo
processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 15
model           : 4
model name      : AMD Athlon(tm) 64 Processor 3000+
...
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext lm 3dnowext 3dnow rep_good nopl eagerfpu 3dnowprefetch vmmcall
...

Dumping core makes the Steam client freeze for a while. So the Steam interface is updated every 5-10 seconds, making it not really usable.

The issue didn't happen before the Dec 13 update.

Does it mean that processor supporting SSE3 is required now?

Steps for reproducing this issue

Launch Steam.
Wait until the main window is shown.

I do have the same problem since mid december 2016:

.local/share/Steam/ubuntu12_64/steamwebhelper.sh: line 5: 19762 Illegal instruction     ./steamwebhelper "$@"

If i remove steamwebhelper.sh while running steam I can use Steam to play games (Library). Of course Store and Community is not working because of the the missing steamwebhelper.sh.

I do also have a AMD Athlon 64 CPU (Newcastle Core) which is missing SSE3 and SSE4.

cat /proc/cpuinfo
processor       : 0
vendor_id       : AuthenticAMD

Any way to make this stop? I can use big picture mode to get around no content loading but the constant core dump has to be filling my hard drive!

Is there any word on anyone looking into this? I would presume no content from the stor (blocking purchasing more games === 💸 ) is a major problem.
