On my system (16.04) there is:
qtchooser: /usr/bin/qdbusviewer
qttools5-dev-tools: /usr/lib/x86_64-linux-gnu/qt5/bin/qdbusviewer
qdbusviewer will try to start
qt4-dev-tools: /usr/lib/x86_64-linux-gnu/qt4/bin/qdbusviewer
but is not installed.
installing requires 146 MB additional diskspace.
/usr/lib/x86_64-linux-gnu/qt5/bin/qdbusviewer works fine when directly
invoked, but from KDE it also doesn't work as it probably starts
/usr/bin/qdbusviewer
I was trying to discover how to replace Spectacle with KSnapshot as I
consider the latter a vastly superior program at least in terms of user
experience.
I realize though you can just use command line options for KSnapshot
just fine.
Spectacle just has a badly designed UI. "Export to" doesn't make sense,
whereas "Send to" does. "Save and exit" with 4 options doesn't make
sense, just "Save" does. "Copy to clipboard" doesn't make sense, whereas
just "Copy" does. The only thing annoying about KSnapshot is that it
maximizes often upon start, and it remembers previous names you have
saved under, giving you confusing filenames upon saving. In this case
KSnapshot iterates and increases the number of the file.
The suffix. It's not very useful unless you explicitly set that as an
option, not as the last filename you saved under. Spectacle will
directly save to disk upon fullscreen mode activation (shift-print) with
a useful predictable name that doesn't make sense but also doesn't
confuse.
I guess many users would prefer the way of making a screenshot without
starting the visible application that Spectacle has, which is something
KSnapshot strangely doesn't offer. Personally I have also chosen to
stick to that - there is no need for a 3rd flag for KSnapshot for me.
-------------------------
Spectacle also has weird stuff like the making a screenshot of the
window under the cursor with no delay and without a mouseclick (you have
to be really fast people) and that this is the default; and that you can
make a screenshot of the active window from the UI by clicking on some
other window after you have activated it (and not the active window
itself) or that "active window" makes sense from the UI at all; why not
just click on it then? Active window is an operation for tool-less
activation, meaning based on a shortcut. It has no place in a UI that is
itself the active window when you use it. (It will take the previously
active window by default, but in that case you could have clicked on it
or used a keyboard shortcut; there is not really a reason to have active
window as an option here.
It will also not work for popup menus, whereas KSnaphost will. It will
leave you with either the main application window (active window mode)
or a blank screenshot (window under cursor mode).
It can also not even snapshot the KDE menu correctly, leaving you with a
transparent image instead of what the user sees (my KDE menu is not
transparent). I am amazed at how much bad stuff I can find for this
program, even though I am trying :p.
Last but not least the "take new screenshot" button is just not in a
comfortable position and the window is too big (and you cannot resize
it) for comfortable use since usually you'd be interested in the windows
behind it, right.
I mean it seems they did everything just about right to make it
dysfunctional. That is also a skill.
Why people have chosen this thing instead of improving on the old? I
don't know. I guess only the name is better (Spectacle). KSnapshot
definitely had (and has) limitations but they would be easy to fix and
apparently no one is doing it. Its visible dialogue layout is also not
that outstanding but it could be improved you know. It's just the
spatial layout of the bottom section though, the rest is perfect. I
seriously have no need for anything other than KSnapshot in addition to
saving in the background, and getting rid of those weird names (previous
save names) and also.
Being able to create snapshots of a window without transparent border.
That's probably a KWin feature, I find it hard to know how to get the
DBus thing working for a single Window on purpose / call. You can't
actually create shadow-less "square" (or rectangular) screenshots of
windows without any extra fluff, but that do contain the window title.
You'd have to turn all kinds of desktop effects off for that every time.
It was worse under the blue glow of KDE 4 I think, because the extra
space you got was even bigger (much bigger). It's pretty workable now.
Anyway those were my opinions for a long time about KSnapshot but now
with Spectacle everything has got worse (apart from the background mode)
(and the name Lol) and I am happy to find that it takes no more than
perhaps 3 hours of working and subsequently writing to a mailing list,
to set it back to KSnapshot.

But PS PS
I just fixed it for now by symlinking the qt5 qdbusviewer to the qt4
one:
sudo ln -s /usr/lib/x86_64-linux-gnu/qt5/bin/qdbusviewer
/usr/lib/x86_64-linux-gnu/qt4/bin
Regards.
