Description

HI,

For a long time (can't remember since when), xfce4-datetime-plugin doesn't show up in panel when XFCE is run, from the very beginning. This happens sometimes. Sometimes the plugin shows up, though. It's more usual that it doesn't than it does.

Obviously this makes the plugin mostly unusable.

I'm running Debian stable (9.5) with security updates. Plugin version is 0.7.0 (dont't know why I can't set this in bugzilla's form).

The plugin is placed on the righmost position of the task bar. It makes no difference if I move it left to other plugins or back (still doesn't show up).

Interestingly it seems to be always running (there's a process with PID even if it doesn't show up). "strace -p PID" shows:

recvmsg(3, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="U\2\350(\350\3336\0\3\20\0\0\20\0\0\0\0\0\0\20\20\20\20\20\0\0\3\37>\3\0\0", iov_len=4096}], msg_iovlen=1, msg_controllen=0, msg_flags=0}, 0) = 32
recvmsg(3, {msg_namelen=0}, 0)          = -1 EAGAIN (Resource temporarily unavailable)
recvmsg(3, {msg_namelen=0}, 0)          = -1 EAGAIN (Resource temporarily unavailable)
poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=5, events=POLLIN}, {fd=7, events=POLLIN}], 4, 5569

This more or less repeats for each keypress. I can strace more if necessary.
