Qubes OS release

R4.1

Brief summary

Chrome allows to install applications and creates launchers. The name of such a launcher contains the guid of the application (?) and the profile name (chrome-agimnkijcaahngcdmfeangnmldooml-Default.desktop). This is too long path to check with the prefix 'qubes-service/app-dispvm.' as qubes.StartApp does. Qubesdb's maximum path is 64, how about expanding to 128/256?

[user@dom0 ~]$ qvm-run -p -a --service -- personal qubes.StartApp+chrome-agimnkijcaahngcdmfeangaknmldooml-Default
Traceback (most recent call last):
  File "/etc/qubes-rpc/qubes.StartApp", line 39, in <module>
    main(sys.argv)
  File "/etc/qubes-rpc/qubes.StartApp", line 15, in main
    if qubes_db.read('/qubes-service/app-dispvm.' + arg) is not None:
qubesdb.Error: (0, 'Error')
