Not sure if this bug is still active, but I can confirm this behaviour
on both 18.04 and 19.10 and also that it is (in my case) caused by a NFS
share from /etc/fstab that disappeared without being unmounted first.
umount -f -l / solved the issue, file open/save dialogs are work
again after that.
It seems to be specific for the GTK open/save dialog. When I for
instance change the dialog in libreoffice to the native non-GTK dialogs,
the problem disappears in this application.

Title:
File dialog extremely slow
Status in gtk+3.0 package in Ubuntu:
Confirmed
Bug description:
From any application where you have a "save as" or "open" option, the
dialog displays, but it takes forever. I have a i5 with 16GB RAM and 2
SSD's, so the machine is not slow. However, if I use gedit and click
open / Other documents it takes 6 to 7 seconds before the file dialog
is properly displayed. This does not even get better with reuse. I
opened gedit just now and the first time it took 7 seconds. Then I
pressed Cancel and repeated the process - it still took more than 6
seconds before the dialog was properly displayed. Often I would only
see "Other locations" and then default places (Home, Documents etc)
and bookmarks (I have about 8 bookmarks of which 2 are network shares)
are displayed. These items are added one by one - maybe one every half
second. Often it takes a few seconds before the first location other
than "Other Locations" is displayed. Even the file panel is not
immediate at first and you can see how lines are added one by one.
Take into account that my home folder is on an SSD, so populating a
file list should be lightning fast. I have looked at the CPU activity,
but it does not go over about 10% during display of open and close
dialogs.
Just be aware that this is not specific to gedit - all applications
using gnome file dialog has the same problem.
Please see the attached screen recording.
