Comment (by gk):

 Looking around I am actually not convinced this is a Tor Browser bug.
 Chrome has even an own error message for that pointing to chmod 1777:
 [4856:4856:0820/085005:ERROR:shared_memory_posix.cc(258)] Unable to
 access(W_OK|X_OK) /dev/shm: Permission denied
 [4856:4856:0820/085005:FATAL:shared_memory_posix.cc(260)] This is
 frequently caused by incorrect permissions on /dev/shm.  Try 'sudo chmod
 1777 /dev/shm' to fix.
