Two other apps that show the problem: pavucontrol and cheese.
I'm using the openbox window manager. I assume the apps are looking for some
sort of reply that a gnome desktop would give them.
In strace, it's waiting on:
poll([{fd=15, events=POLLIN}], 1, 25000)
(the fd 15 for cheese, 11 for pavucontrol).
If I run journalctl -b 0 while pavucontrol is waiting to start, I get
the attached log: I've edited it to show the end of one run of
pavucontrol and then a second run up to the point where it hangs (with
comments interspersed by me). At the end of the previous run, after I
hit ^C, it prints
Failed to create file chooser proxy: Error calling StartServiceByName
for org.freedesktop.impl.portal.desktop.gtk: Timeout was reached
A web search for that message gives a gazillion hits -- lots of people
are seeing this -- but so far I haven't found a solution/workaround.

Title:
Applications delayed on launch
Status in dbus package in Ubuntu:
Confirmed
Bug description:
Hello,
i am unsure if this is really a problem with dbus but my first
research showed it could be related to dbus.
1.)
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 19.10
Release: 19.10
Codename: eoan
Ubuntu Budgie on T460 with 256GB SSD and 16GB RAM

3.) I've expected just "normal" loading applications
4.) Some applications are delayed at startup. The application will
take around 30s to launch, but afterwards it just runs fine. Affected
application I found so far are KeepassXC, Filezilla and OnlyOffice
Desktop-Editor. From strace I saw this applications are stopping (for
about 20-30s) at this point:
connect(12, {sa_family=AF_UNIX, sun_path="/run/user/1000/bus"}, 110) = 0
getpid() = 8165
geteuid() = 1000
getegid() = 1000
getpid() = 8165
geteuid() = 1000
getegid() = 1000
sendmsg(12, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\0",
iov_len=1}], msg_iovlen=1, msg_control=[{cmsg_len=28, cmsg_level=SOL_SOCKET,
cmsg_type=SCM_CREDENTIALS, cmsg_data={pid=8165, uid=1000, gid=1000}}],
msg_controllen=32, msg_flags=0}, MSG_NOSIGNAL) = 1
sendto(12, "AUTH\r\n", 6, MSG_NOSIGNAL, NULL, 0) = 6
recvfrom(12, "REJECTED EXTERNAL\r\n", 4096, 0, NULL, NULL) = 19
sendto(12, "AUTH EXTERNAL 31303030\r\n", 24, MSG_NOSIGNAL, NULL, 0) = 24
recvfrom(12, "OK 7f079149c4e5e774135107445dc85"..., 4096, 0, NULL, NULL) = 37

sendto(12, "BEGIN\r\n", 7, MSG_NOSIGNAL, NULL, 0) = 7
write(15, "\1\0\0\0\0\0\0\0", 8) = 8
eventfd2(0, EFD_CLOEXEC|EFD_NONBLOCK) = 14
write(14, "\1\0\0\0\0\0\0\0", 8) = 8
write(15, "\1\0\0\0\0\0\0\0", 8) = 8
poll([{fd=14, events=POLLIN}], 1, 25000) = 1 ([{fd=14, revents=POLLIN}])
read(14, "\1\0\0\0\0\0\0\0", 16) = 8
poll([{fd=14, events=POLLIN}], 1, 25000
During my first research I found this following to topics related to the
issue:
https://askubuntu.com/questions/1184774/some-applications-on-ubuntu-19-10-very-slow-to-start
This Stackoverflow topic links to the archlinux forum:
https://bbs.archlinux.org/viewtopic.php?id=230036
I can confirm that running the delayed applications with "dbus-launch
--exit-with-session application" or by running it as root they are all
starting without any delay.
Thanks for your help! Let me know if you need any further information.
Best Regards,
Sebastian
