My ldd output is lacking some of the libraries.
libexpat.so.1
libxcb-present.so.0
libxcb-sync.so.1
libxshmfence.so.1
libglapi.so.0
libXdamage.so.1
libXfixes.so.3
libX11-xcb.so.1
libxcb-glx.so.0
libxcb-dri2.so.0
libXxf86vm.so.1
libdrm.so.2

But all of them _are_ installed on my pc.

I cannot reproduce with the pre-compiled binary for 5.8.

Attached is output from ldd after compiling with the pre-compiled
binaries. Note that the path to the pre-compiled binaries for me is (the
default): /home/scott/Qt/5.8. From what I understand, the output from
ldd does show that LyX is using the pre-compiled binaries in ~/Qt and
not my custom-compiled binaries.

I used qt-unified-linux-x64-online.run to install, and I selected all of
the Qt 5.8 components (see attached), and left the default tools
selected (I think Qt Creator).

I don't have many ideas with how to proceed. I was going to suggest you
try 5.9.0alpha but there are no binaries for Qt's alphas.

You could install Ubuntu on a virtual box and then run the lyx-tester
script that I use on it. And then instead of using system from the
repositories (which is what lyx-tester does by default) you can just use
the pre-compiled binary. I think it would not crash for you (since my
system is very similar to the one created when running lyx-tester), and
you could try to see what the difference is between your system and the
virtual box.

Good idea, and since Kornel said the problem shows only when the
libraries are used at run time (and doesn't matter for compile time),
that seems like the easiest way to test.

What is the difference between the following two (the second removes the
prepended "env")?

  env LD_LIBRARY_PATH=/path/to/mylibs prog

and

  LD_LIBRARY_PATH=/path/to/mylibs prog

You can always launch a program "prog" by

env LD_LIBRARY_PATH=/path/to/mylibs prog

to force using the libraries in /path/to/mylibs without tinkering
with ld configuration.

Yes, this is sufficient.
If you want to switch more often, you should create a script.
I have a symbolic link, /usr/BUILD/BuildQt, pointing to the correct QT.
And in /etc/ld.so.conf.d/qt5.conf the first line reads
/usr/BUILD/BuildQtRoot/lib

Also the env PATH contains /usr/BUILD/BuildQtRoot/bin.

In case of using built-in qt, /usr/BUILD/BuildQtRoot is removed.

But to be sure, I always also use 'sudo ldconfig' too.

Yes I will try this when I'm back to my testing computer (I'm currently
traveling). I will have to make sure that my custom compiled Qt does not
interfere. Do I just need to edit

  /etc/ld.so.conf.d/qt5.conf

and run

  sudo ldconfig

?

Next try was to compile QT5.8 from source. Now lyx does not crash.

Scott, could you try to check if the binary-provided qt5.8 crashes on your 
system?

I tried to compile Qt 5.9.0-alpha, but unfortunately I was unable to do it.
Did not even come trough the configuration phase
(You cannot configure qt separately within a top-level build)

Should probably try with Qt 5.8.

I can't reproduce with Qt 5.8.1dev (compiled a few weeks ago).

I'm interested and will test in a week when I'm home and have access to
the computer where I have Qt 5.8 installed.

OK, it does not help. Maybe with the mentioned new snapshot in this bugtracker 
for QT5.8 things will
improve.

Apparently not completely. The article is about Mint18.1, my machine is Mint 
17.3.
But one point may be important. Switching to QT5.8, I never restarted the 
session.

Will try.

I only found this:
https://www.qcad.org/bugtracker/index.php?do=details_id=1545
but they actually state that Qt 5.8 fixes it...

Nice, what is the version of your debian? Which desktop? Googling implies that 
this may be important.
But nothing I tried helped here.

I think that this needs some investigation. I cannot reproduce the
behavior on debian with Qt 5.8.

Looks like nobody seems to to be interested.
For me, the only workaround is to use USE_NATIVE_FILEDIALOG=1.
I don't like it because the native dialog is not so nice as that from LyX,
but at least the so compiled lyx is usable.

Attached patch is for cmake build.

The same change is needed here for branch2.2.
