Bug#1036309: xdg-utils: xdg-mime pauses for around 2 seconds running xprop to detect XFCE

[Reuben Thomas]

Package: xdg-utils
Version: 1.1.3-4
Severity: normal

I was noticing that xdg-mime was very slow on one system; this turned out to
be a server where I did not have a desktop environment, so xdg-mime was
going through all of its DE checks every time. Commenting out the calls to
“xprop” fixed it; perhaps because I was ssh-ing into the system, and hence
xprop was querying my local X server over the net?

In any case, xdg-mime shouldn’t run a command that could wait for multiple
seconds like this, at least not just to diagnose its environment.
