[Pkg-privacy-maintainers] Bug#944823: Failure to open shm and ggx failures.

[shirish शिरीष]

Package: torbrowser-launcher
Version: 0.3.2-2
Severity: normal

Dear all,
I ran an update/upgrade of torbrowser-launcher. While it did the
updates, when it rebooted the browser I got the following at the start
of negotiation of the connection itself.

Nov 16 01:09:47.000 [notice] Bootstrapped 5% (conn): Connecting to a relay
Nov 16 01:09:47.000 [notice] New control connection opened from 127.0.0.1.
[387349, Main Thread] WARNING: failed to open shm: Permission denied:
file /var/tmp/build/firefox-xxxxxxxx/ipc/chromium/src/base/shared_memory_posix.cc,
line 142

and after that I get messages such as below -

Crash Annotation GraphicsCriticalError: |[0][GFX1-]: Failed to lock
new back buffer. (t=0.538819) [GFX1-]: Failed to lock new back buffer.

[387349, Main Thread] WARNING: failed to open shm: Permission denied:
file /var/tmp/build/firefox--xxxxxxxx/ipc/chromium/src/base/shared_memory_posix.cc,
line 142

and then -

Crash Annotation GraphicsCriticalError: |[0][GFX1-]: Failed to lock
new back buffer.

I did try and get a snapshot if /dev/shm is not available but it is -

$ df -h --output=source,target | grep tmpfs
tmpfs          /run
tmpfs          /dev/shm

Also findmnt gives the following -

$ findmnt | grep /dev/shm
│ ├─/dev/shm                          tmpfs       tmpfs
rw,nosuid,nodev

I basically get a black screen which I have attached.
