Public bug reported:
Testing the libreoffice 5.4.0.3 snap on x86-64, the first time around
the app launches fine, but after closing it it won't launch again.
This is because soffice.bin remains as a zombie process and
/snap/libreoffice/current/libreoffice.wrapper never exits.
Upon inspection, the following seccomp denial is what causes the process
to hang:
type=SECCOMP msg=audit(1504011042.386:4724): auid=1000 uid=1000 gid=1000
ses=4 pid=13187 comm="soffice.bin"
exe="/snap/libreoffice/x4/lib/libreoffice/program/soffice.bin" sig=31
arch=c000003e syscall=94 compat=0 ip=0x7fc938d2a327 code=0x0
syscall=94 is lchown, of which there is only one call in the libreoffice
codebase, in attemptChangeMetadata (sal/osl/unx/file_misc.cxx).
